Decoupling control of bearingless induction motor with least squares support vector machine inverse
摘要
Abstract
In order to achieve nonlinear dynamic decoupling control of radial suspension force, speed and flux linkage, a decoupling control strategy was proposed based on least squares support vector machine inverse of bearingless induction motor. According to the reversibility analysis of original system, the inverse model of the bearingless induction motor was approximated by the least squares support vector machine and connected with the original system to construct pseudo-linear system. The pseudo-linear system was equivalent to two independent linear displacement subsystems of rotor speed subsystem and magne-tic flux linkage subsystem. To further improve the performance of whole control system, the closed-loop controller was designed for the pseudo-linear system. Decoupling control performance of the proposed method was simulated by Matlab. The simulation results show that the nonlinear decoupling control of the system is realized successfully with good robustness and dynamic and static performances, and the defects of conventional inverse system method with excessive depending on exact system model are overcome.关键词
