Abstract
The disturbance torque of ocean wave is much larger than that of a rudder,so it is difficult to reduce yaw angle with rudder control and then the number of noneffective rudder will increase in the case of high ocean wave.We employ a course filter to process yaw angle of a course and reduce the impact of main value frequency of ocean wave on a heading control system.The filter will reduce the response of a heading control system to wave disturbance and then reduce the number of noneffective rudder.This will reduce the energy consumption and wearout of a steering.
