Simulation of Induction Motor Direct Torque Control System based on Matlab/Simulink

Xue Jun-wei

Abstract

Direct Torque Control(DTC) System of induction motor was constructed with Matlab/Simulink based on the theory of DTC.The modules for stator flux observation and inverter were illustrated.It was explained how the space voltage vector affected the motor' s stator flux and electromagnetic torque.At last an experiment with definite parameters was emulated and the waveform of stator voltage,stator current,rotor speed and electromagnetic torque were given.
