中文摘要：
在给出磁悬浮开关磁阻电机悬浮系统控制模型的基础上,采用逆系统相关理论求解出磁悬浮开关磁阻电机悬浮系统控制模型的解析逆系统。在原系统的基础上再应用求得的解析逆系统进行复合,建构伪线性系统,对悬浮系统的悬浮力进行解耦。用自抗扰控制器作为径向位置控制器,对复合伪线性系统进行综合,把主绕组电流对悬浮系统引起的摄动视为悬浮系统的一种外扰,利用扩张状态观测器开展动态即时补偿。所设计的自抗扰补偿逆系统解耦方法通过了仿真结果验证,成功实现了悬浮力间的解耦,而且基本消除了转矩调节时主绕组电流的摄动对悬浮系统的影响,控制系统性能优良。
英文摘要：
Based on the radial force control model of bearingless switched reluctance motors （BSRM） , the analytic in- verse system of the radial force control model was given by applying the inverse system theory. Cascading the analytic in- verse system with the original system, the compounded pseudo linear system of BSRM was formed and the primary decou- pling between the radial force was realized. The fuzzy logic controller was proposed as the radial position controller to con- trol the compounded pseudo linear system. Considering the approximation and the uncertainty of the model and the time var- iation of the system parameters, the fuzzy logic compensator was designed to compensating the performance of the primary decoupling. The actual control quantity of BSRM is the sum of the out-put control quantity of fuzzy logic controller and the compensation quantity of fuzzy logic compensator. The simulation results show that the proposed fuzzy logic compensation inverse system decoupling control succeeds in decoupling control of radial force with good performance.
