Course content

The course focus on the design of control systems for various marine operations, motion control, positioning, manoeuvring, machinery systems and propulsion systems for ships and floating marine structures.
Control systems include dynamic positioning, thruster-assisted position mooring, motion damping, crane control, machinery systems, propellers, thrusters, rudders, electrical power generation and distribution for maritime electrical installations. Application areas include shipping, offshore oil and gas, and aquaculture industries. Process knowledge including mathematical modelling is emphasized. Introduction to conventional linear monovariable (SISO) and multivariable (MIMO) control and observer designs (PID, LQG, Kalman filtering, etc.) for marine applications will be given. Results from nonlinear state estimation and control, including passivity, feedback linearization, and Lyapunov analysis, will be presented. It will also be given an overview of the implementation aspects with focus on signal processing. Aspects related to safety and performance of marine control systems as well as authority and class requirements will be treated.

Learning outcome

The course will give an introduction to design of control systems for dynamic positioning of ships and floaters, marine operations, marine automation and electrical power generation and distribution using maritime electrical installations on ships and floating marine structures.

Learning methods and activities

If needed, the lecture will be given in English. All written material is in English. Portfolio assessment is the basis for the grade in the course. The portfolio includes a final written exam (67%) and exercises (33%). The results for the parts are given in %-scores, while the entire portfolio is assigned a letter grade. Postponed/repeated exams may be oral.
