Shaping the Ship Yaw Response by the State-Space Feedback Gain
Abstract:
Ship autopilots are usually designed based on PID controller because of the simplicity and the ease of construct. However its performance in various environmental conditions is not as good as desired. This disadvantage can be decreased by designing a linear state space feedback controller. This paper presents the utility of the state-space feedback controller to stabilize the system and shaping its response as desired. The simulation results for a 4DOF ship with real parameters show the effectiveness of the feedback controller in comparison with ordinary PID ship autopilots.
