Abstract

This article designs a heading control autopilot which contains three parts: a control and display unit (CDU); a steering control unit (SCU) and a algorithm control unit (ACU), adopting the feedback linearization optimal control algorithm in the ACU. The characteristic of this algorithm is that it combines the nonlinear disturbance existing in the ship motion and the ship's feedback rudder angle into a new rudder angle, so that the impact disturbance could be eliminated. This autopilot has completed closed-loop experiments in the lab under the semi-physical situation. According to the test results, the autopilot hardware circuit has high stability, as well as fast operation speed. The control algorithm has the merits of a lower steering number and strong anti-jamming capability.
