| Abstract: | The mathematic model of the synchronous machine was constructed and its control technique of mechanical - sensorless was investigated. The method of inspecting the PMSM rotor position in different conditions was proposed. Voltage and current signals of winding magnetic were used to check the initial rotor position and the position of revolving rotor by a high - frequency current injection and extended Kalman filter method. The space vector control system designing scheme of the permanent magnet synchronous motor based on DSP was presented. |
