【Abstract】 A solution to control a permanent magnet synchronous motor using the TMS320C24x is described. The control method presented relies on the field orientated control. This algorithm maintains efficiency in a wide range of speeds by controlling the rotor flux directly. Within this report different enhanced algorithms are presented. Among the solutions proposed are ways to suppress phase current sensors and using a sliding mode observer for sensorless speed control.更多还原
