Position Control of Permanent Magnet Synchronous Motor via Composite Nonlinear Feedback

摘要：

　　A parameterized design of composite nonlinear feedback controller is proposed for typical second-order servo systems subject to unknown constant disturbance and control input saturation.The control law consists of a linear feedback part for achieving fast response,a nonlinear feedback part for suppressing the overshoot,and a disturbance compensation mechanism for erasing the steady-state error.An extended state observer is adopted to estimate the unmeasured state and unknown disturbance.The control scheme is applied to a permanent magnet synchronous motor(PMSM)position servo system,and experimental tests are carried out using a TMS320F2812 DSP board.The results confirm that the servo system can achieve fast,smooth and accurate position regulation,and has a certain degree of robustness with respect to the load disturbance and system parameter perturbations.
