Abstract
Compared with the conventional rotary motor, the permanent magnet linear synchronous motor (PMLSM) has the advantages of simple structure, large thrust and good fast response. However, due to the linear motor ripple disturbance and positioning force changes will cause thrust fl uctuatio ns, but also aff ected by the end eff ect, slotting force and load changes, system parameter drift, nonlinear friction force, etc., resulting in poor system controllability, which directly aff ects the positioning and trajectory tracking accuracy of the linear motor, by observing the thrust fl uctuations of the permanent magnet linear synchronous motor, By using prediction function and fuzzy control algorithm, the thrust fl uctuation suppression method based on fuzzy prediction function control is established, and the improved prediction function fuzzy controller is constructed. According to the deviation and deviation change rate of the system, the parameters of the fuzzy controller are optimized and adjusted online by using the proportional coeffi cient, so as to improve the comprehensive performance of the linear motor servo system, and provide the theoretical basis and technical approach for realizing the high-performance linear motion system.
