An improved Synchronous Control Strategy based on Fuzzy controller for PMSM
Keywords:Permanent magnet synchronous motor, synchronous control strategy, virtual shaft, fuzzy control
AbstractIn industry, rail gnawing phenomenon often appears in the synchronous operation of crane. An improved synchronous control strategy for a dual permanent magnet synchronous motor (PMSM) servo system is proposed in this paper. To achieve a synchronous performance with robustness, a cross-coupled synchronous system based on the virtual electronic shaft which both torque and speed are used as feedback signals is developed. Two fuzzy PID compensators with accurate approximation capability based on programmable logic controller (PLC) is implemented to estimate the lumped uncertainty. In the computer simulation, the improved synchronous control strategy is proved to have strong ability to adjust for the external disturbance, and have both smaller convergence time and tracking error. Some experimental results are illustrated to depict the validity of the proposed control approach, which can effectively inhibited wheel’s rail gnawing phenomenon in crane.
