This paper describes the implementation of multirate sampling technique for carrier space vector pulse width modulation based direct torque control (CSVPWM DTC) of induction motor (IM) drive with an objective to reduce the electromagnetic torque ripple. The benefit of the proposed technique for CSVPWM DTC based IM drive; it gives lower torque ripple as compared to single rate sampling technique. In...
In this paper, a simple and effective algorithm for direct torque and flux control three phase induction motor drive is proposed. In this method, control technique is based on decouple between amplitude and angle of reference stator flux for determining required stator voltage vector. This proposed method eliminates the estimation of stator flux angle to generate stator voltage vector with constant...
This paper proposes an algorithm for direct flux and torque controlled sensorless three phase induction motor drive systems. This method is based on control of slip speed and decouple between amplitude and angle of reference stator flux for determining required stator voltage vector. Within the given sampling time, flux as well as torque errors are controlled by stator voltage vector which is evaluated...
