Composite control method of PMSM based on fuzzy sliding mode control and harmonic voltage compensator
摘要
Abstract
In order to improve the anti-disturbance capability and steady-state control accuracy of perma-nent magnet synchronous motor control systems,this paper proposed a composite control method integrat-ing fuzzy sliding mode control and a harmonic voltage compensator.To address the inherent chattering is-sue in sliding mode control,a fuzzy sliding mode convergence law was designed.This convergence law utilized the system states to define fuzzy rules that dynamically adjusted the gain of the exponential term.Concurrently,it replaced the fixed parameter in the switching term with an adaptive function,enabling dy-namic adaptation.This design effectively suppressed sliding mode chattering while maintaining system ro-bustness and dynamic response performance.To mitigate the pulsating harmonics issue in the motor con-trol system,a harmonic voltage compensator based on a second-order generalized integral filter was devel-oped.This compensator employed the second-order generalized integral filter to extract harmonic compo-nents present in the stator current signal.Subsequently,it implemented control and provided online com-pensation for these extracted harmonic components.Consequently,current pulsating harmonics within the system were significantly attenuated,leading to enhanced speed control accuracy.Experimental results demonstrate that,compared to the conventional PI control method,the implementation of the proposed composite control method yields a 44.36%improvement in the system's dynamic response speed,a 30.38%reduction in the maximum rotational speed fluctuation during sudden torque disturbance,and a re-duction of the 6th harmonic pulsating component in the q-axis current to 0.77×10-3.These results confirm that the proposed composite control method effectively enhances the system's dynamic response perfor-mance,robustness,and rotational speed control accuracy.关键词
