Abstract: Permanent magnet synchronous motor( PMSM) speed regulation system has been widely used in various fields. PMSM speed regulation system based on advance digital signal processing( DSP) of TMS302F28335was designed. The principle of the direct torque control of PMSM and the method of stator flux estimator used low-pass filter( LPF) were introduced. The scheme of start current limited by zero vector in software was simply mentioned.The simulation and experimental results showed that the proposed scheme could solve the problem of large start current. The designed speed regulation system has good dynamic response,simple control structure,and good performance in low speed.
