PMSM自适应模糊滑模转速控制器设计
|
摘要
针对时变的、非线性的永磁同步电机(PMSM)系统设计了一种转速控制器。利用滑模控制鲁棒性、抗干扰强的特点,结合自适应控制抑制系统参数不确定问题时的优势,采用模糊控制理论减小滑模的抖振,设计了PMSM系统的自适应模糊滑模转速控制器。首先介绍了PMSM在静止dq坐标系中的电机模型,分别建立了转速滑模及模糊控制器,给出了自适应律,定义了系统的Lyapunov函数,并证明了稳定性,最后以某型PMSM为例进行了仿真验证,结果表明所设计控制器较传统滑模控制抑制抖振效果佳,控制性能好。
A new rotating speed controller is proposed as the time variety and nonlinearity of PMSM. According to the characteristics of robust and anti- disturbance of sliding mode variable structure control,combing with the advantages that adaptive control conquers the uncertainties of system parameters,including application of the fuzzy control method which is suitable for cutting down the problem of chattering,an adaptive fuzzy sliding mode variable structure rotating speed controller is designed. At the beginning,the model of PMSM under the d- q reference frame is introduced,then the sliding mode controller and the fuzzy controller are set up,the adaptive rule is presented,and the Lyapunov function is defined,the stability of the PMSM is demonstrated,finally a type of PMSM is taken for example,the simulating model of PMSM including the designed controller is set up,the results show that the new controller has fine capabilities of conquering chattering and good control performances.
