Interpolated versus Polytopic Gain Scheduling Control Laws for Fin/Rudder Roll Stabilisation of Ships

Abstract : Taking into account the variations of the environment of ships is a means of improving performances of roll stabilisation systems; this can be done through the use of gain-scheduling (GS) control law. In this study, a GS-control law is obtained by interpolation of fixed HP controllers which have been synthetized for different sailing conditions of the ship represented by linear models. The GS controller depends on the ship speed and on a stabilisation quality factor. It is compared to a previously synthetized HP LPV controller (Linear Parameters Varying). Simulation results are given.
