【Abstract】 The hardware circuit design of a DSP-based AC servo system is given, which includes a power board, a driver, an extended memory, a current loop and a speed loop.Cheap resistors are used to sense three-phase currents of the PMSM and an IGBT module CPV363M4K is used to compose the inverter. The TMS320F243 made by TI is chosen to implement the AC Servo System.更多还原
