基于模糊补偿的无轴承同步磁阻电机径向位置逆控制
Inverse Control of Radial Position for Bearingless Synchronous Reluctance Motor Based on Fuzzy Compensation
摘要
Abstract
Control model of the rotor radial position for bearingless synchronous reluctance motor was introduced,in order to deal with the multivariable,strongly coupled and nonlinear system in the rotor radial position, the inverse control scheme of the rotor radial position based on fuzzy compensation was presented, the inverse system's existence was proved,and the inverse model was derived,then the inverse model was accurately linearized into a pseudo linear system,so the system of rotor radial position can be decoupled into two second order linear integral subsystems. In order to synthesize the decoupled system, the closed fuzzy compensator which includes PID controller and fuzzy controller was designed,the fuzzy compensator not only can real-time compensate the decoupled effectiveness but also improve the robustness of the control system. Simulation results demonstrate that the rotor can realize a successful magnetic suspension with the proposed method, the control system has good dynamic and static decoupling characteristics.关键词
