Abstract

To solve the problem of rotor unstable suspension which suffers from the influence of rotor resistance variation in air-gap-flux oriented control system for the bearingless induction motors, a rotor resistance online identification technology based on the suspension control loop is researched, and the air-gap-flux oriented optimized control strategy based on rotor resistance online identification is proposed. To further improve the static and dynamic system performance, a fuzzy PI speed controller based on fuzzy control theory is designed to revise the parameter of PI controller. The Simulation results show the efficiency of the proposed air-gap-flux oriented optimized control strategy.
