中文摘要：
针对磁悬浮开关磁阻电机内部非线性强耦合问题，研究了一种基于线性二次型最优逆系统的磁悬浮开关磁阻电机解耦控制新方法。通过对电机结构与工作原理的分析，基于等效磁路法和虚位移定理建立了考虑转子偏心和耦合的悬浮力模型。利用Interactor算法分析了模型可逆性，基于逆系统理论求解了系统状态反馈规律，获得了悬浮力的解析逆模型，与被控对象串联构成伪线性复合系统。在此基础上，引入线性二次型最优控制策略对复合系统进行反馈补偿，并对控制器参数进行优化选取，提升了控制性能和能耗，最后对所提方法进行解耦控制仿真和实验研究，并对结果进行了分析与讨论，验证了所提算法的有效性和可行性。
英文摘要：
To overcome the nonlinear and strong coupling features of bearingless switched reluctance motor （BSRM）, a decoupling control method for BSRM using linear quadratic optimal inverse proposed in the paper. First, the principle of radial force production in BSRM was precision radial force model considering the eccentric and system method was explained and the coupling was derived. Then, the inverse system method was adopt to realize the linearization and decoupling of BSRM. The reversibility of radial force model was analyzed by Interactor algorithm, the feedback law was designed, and the analytical inverse model of radial force was obtained, consequently, the linearization and decoupling of BSRM was realized by the inverse model. In addition, a linear quadratic optimal eontroUer was designed combined system, the controller parameters were performance and energy consumption was achieved. verified by the simulation and experiments. optimized by simulation for closed-loop research, the control of the good control Finally, the effectiveness of the proposed method was
