Aiming at the requirements of high-precision speed control and system with high reliability of the modern high-performance permanent magnet synchronous motor( PMSM) control system, a PMSM control system with high speed and high reliability was designed. The system used DSP and CPLD as the core controller, combined with three independent H-bridge inverter drive circuits, and designed current detection circuit, current protection circuit, main voltage detection circuit and rotor position and speed detection circuit, realized the high-speed control of the PMSM. The experimental results showed that the resolver signal was very good, overcurrent signal’ s response was very fast, and the PMSM could be stable when operated at the speed of 10 000 r/min. Besides, the system also had the characteristics of high output power, superior load capacity, smooth running, quiet and so on, which proved the feasibility of the design.
