Torque Control of I. M. Using V/F Method

This paper presents a variable voltage variable frequency (vvvf) method torque control of induction motor modeled in the synchronously rotating dq reference frame using V/f PWM technique Hence induction motor to generate supply torque closely matching with demand torque resulting in elimination of flywheel. Design of an any process machine with flywheel for certain demand torque characteristics introduces torsion vibrations in the power transmission system of any process machine. This method should reduce fatigue in the components of power transmission system thereby prolonging equipment functional failure. The results obtained show a superior performance in the two basic mechanical characteristics: motor speed and electromechanical torque. The performance of this proposed scheme is presented in MATLAB/SIMULINK
