[Abstract]:Aiming at the problem of strong coupling between electromagnetic torque and radial suspension force of bearingless synchronous reluctance motor, various decoupling control methods are analyzed and studied. This paper introduces the rotor suspension principle and mathematical model of bearingless synchronous reluctance motor, summarizes the decoupling control strategy of bearingless synchronous reluctance motor at home and abroad, analyzes the feedforward and feedback compensation control, inverse system control and neural network inverse control. The principle, performance and limitation of decoupling control strategies such as support vector machine inverse control, differential geometric exact linearization control, torque and suspension force direct control are discussed. The development direction of these control strategies is discussed. According to the characteristics of bearingless synchronous reluctance motor, the future research direction of bearingless synchronous reluctance motor is pointed out. The intelligent control is used to increase the anti-interference ability of the system, the parameter optimization design of decoupling controller and the strategy of direct control of nonlinear system with nonlinear control theory.
