Abstract :
Repetitive control is used to zero speed ship roll stabilization system based on pid controller, repetitive control can improve system control accuracy, so is a good method to settle periodic disturbances. From the simulation figure, it can be seen that the effectiveness of roll stabilization is better than before. From another point, repetitive controller can increase roll stabilization effectiveness under the same power consumption.
