Abstract: A simulation model of direct torque control system for base|speed range was proposed, which introduces some novel modeling methods with clear idea and easy realization. The design of PI speed regulator is changed to improve the properties of the flux and torque of the system due to the affect of PI parameters to the system. Also the simulation model based on MATLAB/SIMULINK is given and some simulating results are presented to demonstrate this model is true and can realize the smooth translation between the flux track of hexagon and approximate circle, which has the advantage to refer in the study.
Key words: direct torque control; base|speed range; MATLAB/SIMULINK; simulation; PI regulator
