| Abstract: | In this paper, the simulation models of direct torque control （DTC） systems of induction motors with two flux linkage control modes are established by Matlab/Simulink, i.e. hexagon flux linkage control mode and approximate circle flux linkage control mode. The result analysis and comparative study are also carried out. On this basis, a full speed range of DTC simulation model is established and verified by combination and smooth transition of the two control models. The result proves that the proposed scheme is feasible and correct. |
