A comparison of control systems for ship roll stabilisation

This paper presents the results of a fin-rudder controller synthesis for roll reduction where different types of controllers are tested and compared. Three different main types of controllers including PID, advance phase, dual loop transfer recovery (LTR) and sliding mode (SMC) controllers are considered to stabilise the ship motion. The system comprises three different controllers, fin and rudder controllers, and autopilot. Therefore, for each situation of the ship journey, the triple controllers should be designed. It is not necessary to have the same controller structure for all three submodels. This paper compares these various controllers individually for each submodel, and demonstrates the results of the implementation of controllers with different structures when applied to the entire system.
