摘要
PMSM电机具有时变?非线性的特点,利用滑模控制鲁棒性好?抗干扰性强的特点,可以较好地控制电机?但是抖振问题一直是制约PMSM滑模控制系统性能的主要因素之一?本篇论文中针对此问题,提出了一种基于新型趋近律的控制器设计方案?论文主要对传统的指数趋近律进行改造,首先在数学结构上对趋近律进行分析,论证了它的可行性?而后又基于新的趋近律,设计出新型的滑模控制器用来替代传统的滑模控制器?最后论文通过仿真结果,表明新型控制器在动态性和稳定性上优于传统的滑模控制器?
PMSM motor has time-varying and nonlinear characteristics,and can be well controlled with its robustness of sliding mode control and anti-disturbance ability.But the chattering problem has been one of the main factors restricting the performance of the control system of PMSM synovial membrane.Aiming at this problem,this paper proposes a design scheme based on a new reaching law controller.The paper firstly analyzes the traditional reaching law in terms of mathematical structure and proves its feasibility.Then based on a new reaching law,design a new controller of synovial to replace the traditional PI controller.Finally,the simulation results show that the new controller,PI controller is superior to traditional one in dynamic performance and stability.
