Research And Design Of AC Servo Drive System Based On DSP

With the development of AC servo related technology, the digital AC servo systems using permanent magnet synchronous have been widely used in the high-precision motion control and drive field. Therefore, the study of permanent magnet synchronous AC servo drive system based on DSP has an important practical significance.First of all, this paper presented the development survey of AC servo system, analyzed the structure character of PMSM, and illustrated its mathematical models. Then the article studied the theory of vector control on PMSM further deeply, proposed some control strategies, and simulated on the system. Finally, using the DSP chip TMS320LF2407A to complete the design of the system's hardware and software.
