摘　　要：研究开关磁阻电机滑模观测器间接位置检测方法,针对传统滑模观测器存在抖振影响系统动态性能的问题,引入模糊控制,用模糊控制器调节开关函数的输出幅值,以抑制抖振并快速到达滑模面。详细分析了基于电磁转矩的误差函数构造方法及其选取过程,该误差函数能反映电机转子位置误差与转速误差,讨论了滑模观测器稳定运行条件及参数选取,在此基础上推导了模糊控制规则,设计了模糊滑模观测器。通过仿真和实验分析,验证了模糊滑模观测器能柔化控制器的输出信号,使响应速度更快,且鲁棒性强,可以实现转子位置的精确估算。A study SRM is presented. the the on indirect detection technique of rotor To solve the problem that the chattering position based on sliding mode observer for in traditional sliding mode observer will affect system dynamic performance, the fuzzy control was introduced in sliding mode observer through which output amplitude of switch function was regulated, so the chattering was suppressed and the sliding mode surface was reached quickly. The construction method and the selection process of error function re- flecting the position error and speed error based on electromagnetic torque were analyzed in detail. Then the steady-state operating conditions and parameters selection of sliding mode observer were discussed, on the basis of which the fuzzy control rule was deduced and the design scheme of fuzzy sliding mode observ- er was also proposed. The simulation and experimental analysis verify that the fuzzy sliding mode observer softens the output signal of controller, make the speed responses faster and the system robustness stronger, and realizes precise estimation of rotor position.
