Abstract
According to the theory of asynchronous motor direct torque control,a design method of direct torque control of asynchronous motor using TI′s DSP chip TMS320F2812 was introduced. A low-pass filter with amplitude compensation was used to estimate the stator flux,which filled the defect of pure integration in the U—I model. The software′s interrupt program,speed measurement program,speed adjustment method were given,and the test under CCS debugging environment was given. As a result,the performance characteristics of the direct torque exhibited by the test results were analyzed in detail. The results show that the design method proposed obtains a good control effect in the dynamic and static performance of the system.关键词
