无轴承同步磁阻电机逆系统的解耦控制
Decoupling control based on inverse system for bearingless synchronous reluctance motor
摘要
Abstract
A deeoupling control approach based on α-th order inverse system method has been developed for a bearingless synchronous reluctance motor(BSRM), which is a nonlinear, strong-coupled, multiple-input and multiple-output system. The working principle of radial suspension forces for the BSRM is explained and the mathematical models are derived in detail. Using α-order inverse system method, the original system is decoupled into one first-order linear integral subsystem and two second-order linear integral subsystems. The linear system theory is applied to design the closed-loop controllers. Simulation and analysis have been carried out for investigating the step response, rotor suspending forces,decoupling control, etc. Results validate the dynamic decoupling control among the electromagnetic torque and two radial suspension forces with desirable dynamic and static performances.关键词
