The course focuses on mathematical modelling and design of control systems for various marine operations, motion control, positioning, manoeuvring, machinery systems and propulsion systems for ships, underwater vehicles and floating marine structures. This includes 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 are shipping, offshore oil and gas, fisheries and aquaculture, and ocean science. Process knowledge including mathematical modelling is emphasized. Introduction to conventional linear monovariable (SISO) and multivariable (MIMO) control and observer designs (PID, LQG, Kalman filtering, hybrid control, etc.) for marine applications will be given. Methods for design and operation of autonomous ships and underwater vehicles will be introduced. This includes situational awareness and risk-based control. It will also be given an overview of implementation aspects including signal processing, filtering and signal detection. Methods for analysis and design of time-discrete control systems, including sampling of time-continuous systems, input-output models, z-transform, poles and zeroes, stability analysis. Aspects related to safety and performance of marine control systems, and authority and class requirements will be treated.
