英文摘要： Both the structure and characteristics of the synchronous motor control system, and the characteristics of non-cross-coupled multi-motor drive system are investigated in this project. Considering the uses of AC motor drives in multi-motor drive system and the large differences of the axle load disturbance,a new cross-coupled multi-motor drive system structures is proposed which can achieve good dynamic and static performance. Aimed to the performance of the multi-motor synchronous system which composed of multi-permanent magnet linear synchronous motor, a sensorless control method that based on the whole speed range is provided. A sliding mode speed controller and a sliding mode position controller are designed, and then the system's simulation model is built. Furthermore the validity of design scheme is confirmed by the analysis of simulation and the result of test. The results of the project will provide a valid model and analysis method which based on Mechanism Investigation and Practical Engineering Application for multi-AC PMSM. It has the important academic value and vast potential for future development.
