This paper presents an improved DC voltage source used in a direct torque control system.With the variations in the DC supply voltage,it is easy to alternate the input DC voltage of the converter and control the rotating speed of stator's magnetic flux.Accordingly a fuzzy speed controller is designed to greatly simplify the design of the system and its calculation.The simulation shows that the system has the features of fast response,good robustness and a wide range of regulated speed.
