Abstract

In robust controller design, controllers intend to achieve the best control performance in the presence of the worst uncertainties, and the use of a high controller gain is the general method to handle the effect of uncertainties in nonlinear control theory. However, such a strategy causes massive control actions, so very powerful actuators are demanded to perform unnecessarily large control actions. Furthermore, the robust control performance is mostly obtained at a price of sacrificing the nominal control performance of the system, because the nominal control performance is not taken into account in robust controller design. Therefore, a control method is required to maintain the nominal control performance in the absence of uncertainties and exhibit robust control performance in the presence of uncertainties. In this talk, I will demonstrate two methods: 1) a real-time optimization-based nonlinear observer to estimate not only unmeasurable states but also unknown parameters 2) a self-learning disturbance observer. In the first method, a nonlinear moving horizon estimator is designed for systems that have constrained states and parameters. In the second method, the basic nonlinear disturbance observer is used in the estimation scheme for the self-learning disturbance observer to provide a conventional estimation law, which is used as being the learning error for the neuro-fuzzy system (NFS). Thus, the NFS learns uncertainties, and eventually takes the overall control of the estimation signal completely in a very short time and gives unbiased estimation results for the disturbance. A few real-time implementations on custom-design agricultural robotic systems will also be introduced.

Room B343, Elektro Bld. D, Gløshaugen

Abstract

Reachability analysis is critical for obtaining formal safety and performance guarantees for nonlinear and hybrid dynamical systems. However existing computational tools do not scale to models with more than a few state variables. In this talk we present a scalable procedure to compute tight over-approximations of reachable sets.  We first sample a number of trajectories of the system and next establish a tight bound on the divergence between the samples and neighboring trajectories using the concept of matrix measures from contraction theory. The divergence bounds also account for the accumulation of numerical simulation errors along simulation traces, which means that the proposed method provides a guaranteed over-approximation of the reachable set.  We demonstrate that the proposed technique scales well to systems with a large number of states.

Guest lecture by Andreas Bartl, Technical University of Munich, Germany, on Real-Time-Substructuring: Towards a Hardware-In-The-Loop approach in Structural Mechanics

27 April at 12:30-13:30
Havrommet (A1), Marine Technology Centre

Abstract

Real-Time-Substructuring is a Hardware-in-the-Loop technique in the domain of structural mechanics, which combines physical tests with simulations. Applied to noise, vibration and harshness problems, Real-Time-Substructuring allows testing components of complex systems and their effects under realistic boundary conditions. The method can be used in cases where the setup of the full system in the laboratory requires high efforts and costs or where the virtual component is modified frequently during the design process. The Hardware-in-the-Loop concept allows to take into account non-linear effects of the physical component as well as effects, which are not included in the model, such as temperature changes during the test. Real-Time-Substructuring can enable a rapid prototyping approach as modifications on the physical component show direct acoustic and vibrational effects on the physical system.

In the talk, current research on Real-Time-Substructuring at the Chair of Applied Mechanics at the Technical University of Munich will be presented. A use case, which is currently worked on, is the design process of an automotive transmission crossbeam. Additionally, control strategies for Real Time Substructuring, which are used at the Technical University of Munich will be presented.

Abstract

Autonomous and wirelessly connected vehicles face various challenges before effective commercial deployment. Key among these challenges is accurate and reliable awareness of world interactions. Awareness arises from onboard sensors and from ubiquitous communication between vehicles and infrastructure. Vehicle coordination and safety specifications necessitate reliable “where-in-lane” (i.e., decimeter accuracy) knowledge of vehicle position relative to other vehicles and the environment. This presentation will address vehicle state estimation with a focus on high precision and reliability.

Sensor fusion is critical to achieving these application requirements. Several of the sensors (e.g., vision, radar, Lidar, ultrasound, Global Navigation Satellite Systems (GNSS)) have various spurious measurement types. Standard Extended Kalman Filter (EKF) approaches are not sufficiently reliable at removing the effects of such spurious measurements because the EKF approach must decide at the time each measurement arrives whether it is valid. If deemed as valid, the measurement is used and discarded; otherwise it is not used and discarded. When that decision is wrong, either measurement information is lost or the state and covariance estimates are corrupted. Either situation can result in divergence of the EKF.

An alternative is to maintain all recent measurement data within a moving time-horizon. This window of data can be processed within a Bayesian framework to extract the optimal state trajectory estimate over the time-horizon. Because the time window of data is maintained it is straightforward to change the assumptions as to which data are valid and reprocess the data, allowing consideration of multiple fault scenario assumptions. Therefore, this approach is referred to as a Contemplative Real-Time (CRT) estimator. It is closely related to Moving Horizon Estimation (MHE) and Simultaneous Localization and Mapping (SLAM). This presentation will review the interrelationships between the EKF, Iterated Extended Kalman Filter (IEKF), and CRT within the Bayesian framework; discuss fault accommodation; present comparative experimental results; and discuss recent results on computationally efficient carrier phase integer ambiguity resolution over time windows.

Abstract:

Today we are witnessing a growing need to high-rate data transmission in underwater missions in a wide range of application areas. In particular, with the increasing use of robotics in underwater missions and the recent advances in the design and development of AUVs, there is an urgent need for broadband underwater links.  Recently, visible light communications have received particular attention due to their potential in providing very high-rate data transmission. In the challenging underwater context, the major impairments of the communication link include high beam attenuation, especially in high turbidity waters, and link misalignments. We provide an overview on VLC systems in underwater environments and explain the main considerations on the impact of the underwater channel and the transmission schemes. We present the current research activities in Fresnel Institute and also some future research directions for improving the performance and reliability of these links.

Auditorium T2, Marine Technology Centre

Abstract

Sloshing tests are performed on a rectangular tank filled with bottom-mounted vertical cylinders, around the natural frequency of the first sloshing mode. The numbers and heights of the cylinders are varied. From the position of the resonance peak an experimental dispersion equation is derived, and compared with different formulations from literature. A new formulation is proposed. A modal approach is then applied to derive the RAO of the sloshing response, and compared with the experimental results.

Room B343, Elektro Bld. D, Gløshaugen

Abstract: 

Multiple unmanned aerial vehicles (MUAVs) can provide significant reductions in manpower and risk to humans for Intelligence, Surveillance, and Reconnaissance (ISR), including: enhancement of ISR coverage; increase in the mission success rate; increase of autonomy; robustness and benign degradation in performance. Using a swarm of UAVs has been receiving attention for a variety of applications to take advantage of its inherent flexibility and versatility. The focus of this talk is airborne monitoring of ground traffic behaviour by multiple UAVs in order to detect disguised threats and then to notify the human commander about the potentially dangerous vehicles. Within this traffic the most difficult challenge is to recognise behaviours of the potentially dangerous vehicles, disguised as legitimate traffic. Most of these activities of the dangerous vehicles are characterised by occasional deviations from motion characteristics of the legitimate traffic. For such ISR mission to be successful, the overall autonomy should be able to provide continuity of tracking of the vehicles of interest and thus enable positive identification of suspects.

Abstract:

In this presentation I will discuss target tracking problems that we have encountered while collaborating with biologists. The purpose has been to simplify the biologists everyday work, by automating otherwise time consuming manual labor.  Target tracking is generally considered a mature research field; with well established statistical methods that can be used more or less out of the box.  However, the majority of the available literature deals with surveillance scenarios where vehicles or aircraft are tracked.  Tracking of animals and other natural phenomena, which often is the objective for biologists, is less well covered in the standard tracking literature and result in new challenges.  Examples will be presented of how to extended standard methods to better handle the encountered problem formulations; eg, by introducing a new constrained motion model to be able to follow dolphins in a partially occluded basin, or extracting visual queues to detect the take-off time and direction of migrating birds in Emlen funnels.  Though going slightly outside the standard methods, these tricks fit nicely into the general tracking framework.
