This work implements a direct torque control with space vector modulation scheme on a 200hp induction motor using MATLAB/SIMULINK environment for better dynamic response. The scheme is implemented with voltage source inverter. Further, the scheme uses stator flux based calculator and depend only on stator resistance and on no other parameters. Thus, making it a simple scheme, as computational steps and dependence on many machine parameters will be reduced. Further, the result of direct - torque – control scheme have been compared with field - oriented control scheme on the same induction motor, and showing that the results of direct- torque-control are superior / better than field- oriented control. The work embodied in this paper established that direct torque control is better control scheme for induction motor drive system.
