Simulation and modeling of feedback field oriented control of asynchronous machines

This paper focuses on the field oriented control (FOC) of induction machine. When this technique applied to induction machines, a torque response like DC machine may be achieved, making the induction machine a viable candidate for applications previously dominated by other electric machines so the basic of separately excited DC machine has taken to understand the FOC. The FOC technique needed to achieve the desired performance for which it works on two synchronously rotating axis which are converted by two and three stationary axis by using particular transformation theories. This paper presents a new feedback field oriented (FFO) controller, for which voltage model flux estimator and current model flux estimators are designed, with improved accuracy and stability. These estimators implemented into a FFO controller using various subsystems. The resulting controller achieved an acceptable level of performance over a range of operating conditions.
