A GAIN SCHEDULED CONTROL LAW FOR FIN/RUDDER ROLL STABILISATION OF SHIPS

International audienceTaking into account the variations of the environment is a means of improving performances of roll stabilisation systems. The ship behaviour is modelled as a MIMO LPV system. A methodology is presented which leads to a gain-scheduled control law. The synthesis is based on multi objective optimisation, and on the representation of the standard system as a polytopical system, which depends on ship speed and on a stabilisation quality factor. Simulation results are given
