Rudder roll stabilization using generalized predictive control for ships based on genetic linear model

The rudder roll stabilization RRS is a new technology. The current linear model of ship is adopted to design its controller, but the controller has not a satisfying performance. According to the nonlinear model of ship, a genetic linear model is built adapted to rudder roll stabilization using genetic algorithm. On the basis of the genetic linear model, a generalized predictive controller is designed. The system simulation is given under the typical navigation condition. The simulation shows that the controller performance of genetic linear model is superior to the general model controller. The simulation results indicate that the genetic linear model is feasible.
