PMSM Model-Free Adaptive Sliding Mode Compensation Predictive Control
Aiming at the problem that using model predictive control method designs controllers which relies on the mathematical model parameters of PMSM in vector control system.It will cause the parameters mismatch of controllers and motor when the pa-rameters change at process of running.Thus the control performance is poor.So raising a method celled model-free adaptive pre-dictive control.The predictive model is established by using the input and output data of the system and the time-varying pseudo-partial derivatives;because model-free adaptive predictive control method has no feedback correction link and is susceptible to ex-ternal disturbance.A new high-other sliding mode compensator is designed as correction part,which is used to enhance robust-ness of control system and restrain sliding mode chattering by itself.Finally,MATLAB simulation proves the superiority of the model-free adaptive high-order sliding mode compensation predictive control method.
