Course content

The course is given every second year, next time Fall 2021. 

Guidance, navigation and control (GNC) systems for ships, aircraft, spacecraft and unmanned vehicles including AUV, UAV and USV systems. The course is given as three modules:

  1. Guidance systems and path planning. Determination of the desired path of travel from the vehicle's current location to a designated target, as well as desired changes in velocity, rotation and acceleration for following that path. Introduction to motion planning based on computational geometry (CG) and optimal control (OC). Analysis of path properties relevant to robotic applications.  Conventional path-following algorithms (Dubins paths, clothoids, Pythagorean Hodographs, Fermat’s spirals, splines) followed by state-of-the-art hybrid solutions, which combine CG and OC. Path planning, guidance and control in a a cascaded-systems perspective. Brief overview of line-of-sight (LOS) guidance laws and their variations. Alternative guidance and control architectures, which combines reinforcement learning with optimal control, as well as deep reinforcement learning. Incorporation of collision avoidance algorithms in the aforementioned architectures.  
  2. Navigation systems.   Methods for determination of the vehicle's location and attitude with emphasis on advanced inertial navigation systems (INS). Mathematical models for inertial sensors error characteristics including noise, bias, scale factor and cross-coupling errors. Vibration induced inertial measurement errors. Coning and sculling. Angular velocity and specific force sensor outputs versus incremental sensor outputs. Anti-sculling and anti-coning algorithms. Position and attitude representations. Strapdown equations and accurate numerical implementations. INS aiding techniques and sensors. Error state and extended Kalman-filter formulations for integrated navigation systems. Complementary and nonlinear-observer-based navigation filters. Exogenous Kalman filters (XKF) and Invariant extended  Kalman filters for navigation.
  3. Control systems. Advanced motion control systems for vehicles with focus on watercraft and aircraft. Methods for nonlinear and adaptive autopilot design. Robust motion control systems including conventional sliding mode control and super-twisting adaptive sliding mode control. Hybrid MPC and reinforced learning (RL). Nonlinear attitude control on SO(3).
