Position Accuracy Improvement of PMLSM System Based on Artificial Immune Algorithm

This paper suggests that the artificial immune algorithm can be used effectively on tuning of a PID control structures for PMLSM system. Because of perfect learning, adaptability and efficient pattern recognition, the data process ability of PMLSM was improved, which result in the improved position-precision and robustness of PMLSM. The results of simulation indicate that the proposed control scheme has stronger robustness and better rapidity, and smaller dynamical synchronous error. The artificial immune algorithm is effective to PID tuning.
