【Abstract】 The state feedback control is used for servo system. In order to improve the robustness of the system, a servo-compensator is also designed with internal model principle. Then poles of closed-loop are rationally selected and a expected closed-loop state equation is obtained to correct state controller and state observer. Compared with the method of PID control, the simulation results show the system has higher robustness and better characteristic and the method is quite effective.更多还原
