Research on Ship Course Control Based on Course Signal Filter

In the case of high class ocean wave, because of the disturbance movement of ocean wave is larger than moment of rudder, it is noneffective to reduce yaw angle with rudder control and it also increase the times of noneffective rudder. In this paper design a filter to deal with yaw angle and reduce the main value frequency impact to heading control system. Filter will reduce the response of heading control system to wave disturbance and then reduce the noneffective rudder. It will reduce the abrasion of steering and energy consume.
