Based on the basic theory of direct torque control,low speed performance of direct torque control system is analysed,the major facts influencing low speed performance are gained,to solve the problem.Approximate rotundity flux linkage control method is put forward.By using the Matlab/Simulink,the simulation models of approximate rotundity flux linkage control method are made,and the simulation results are analysed.Practical circuit is designed and the experiment is done by using DSP.The experimental results indicate that in low speed scope the system has excellent dynamic and smilc predormances,little pulse and harmonic.
