【Abstract】 In purpose of the realization of high-performance asynchronous motor control, the direct torque control combining the characteristics of both flux model and torque control was discussed while implementation of the voltage space vector method was discussed too. A direct torque control was achieved through the DSP (TMS320LF2407). By means of detection of the inverter circuit output current to analyze the control effect. The experiment proved the feasibility and correctness of this program, becoming a practical reference to the design of DSP system.更多还原
