【Abstract】 The working principle of permanent magnet synchronous motor was analyzed,and a high performance AC servo system based on S3 C2440 control was designed by using the advantage of the hardware and software of the S3 C2440 chip. The hardware of the system mainly included control module,drive module and current detection module,which simplified the complexity of the circuit. The closed-loop PI vector control strategy of current loop and velocity loop was used.The experimental research of servo system was carried out and the experimental results showed that the control precision of the servo system has been improved.更多还原
