【Abstract】 Feedback filter of internal model control is usually one\|degree-of-freedom. The adjustment of parameters is balanced by disturbance rejection and robustness. Internal model-PID cascade control scheme is proposed by combining the internal model control with the cascade control, PID controller adjusts the system’s disturbance rejection and internal model controller adjusts robustness. The adjustment of control parameters is easy. Theoretical analysis and simulation states the system has good disturbance rejection and robustness.更多还原
