| Abstract: | The research introduced the basic principles of Motor Direct Torque Control and main components,and improved the traditional flux comparators and switch status table with multilayer stagnant ring comparator as well as using chopped vector instead of the reverse voltage vector and using a circular flux trajectory control method.Induction motor direct torque control simulation models was constructed with MATLAB 7.7.Simulation results show that the control model is feasible and correct. |
