| Abstract: | The ship course control system model with uncertainties is first given in this paper. The design result of a traditional PID controller is given based on the nominal model. According to the related theories of LMI processing method for robust controller design, a robust output feedback controller is designed which satisfies the performance index requirements. The compared simulation results show the advantages and practicality of this design method. |
