In this paper, a mathematical model of the speed loop of permanent magnet synchronous motor (PMSM) was constructed. The PI parameters were tuned by the method commonly used in engineering practice, and then the capability of system was analyzed. The differential regulation is introduced to constitute a high performance speed loop of PMSM and realize the perfect following capacity of high speed variation. The PID parameters were tuned by a new optimization tuning method based on phase margin. In this paper, the tuning formula was derived from the concept of phase margin. Furthermore, twice optimization algorithms were called for PID parameters tuning. Com-pared with the traditional PM method derived from geometrical graph, it is simple and pellucid.
