Abstract：For the problem that the performance of heading control system deteriorates due to the change of ship motion charac-teristics with ship speed and load,a design method of heading control system based on least square algorithm is proposed in this pa-per.The least square algorithm is used to identify the parameters of the ship motion model online,and the identified K and T param-eters are used to dynamically adjust the parameters of the heading control system,so as to improve the adaptability of the control sys-tem to the changes of the ship motion characteristics.The simulation environment is built based on Matlab/Simulink simulation plat-form,and the closed-loop simulation is carried out on the ship heading control system.The simulation results show that the pro-posed identification method can accurately identify K and T parameters,and the heading controller based on the dynamic adjust-ment of identification parameters has better control performance for the change of ship motion characteristics.
