Field Oriented Control of Induction Motor

Abstract

In this research, model of a three phase induction motor has been derived using mathematical modeling principles. The model has been implemented using MATLAB Simulink software. Based on indirect field oriented control principles, the controller has been designed and implemented using MATLAB Simulink Software. Designing controller in d-q synchronously rotating reference frame made phase variables (voltage, flux and current) appear as DC time invariant components and prevent controller from saturation. Torque and flux linkage were targeted to be controlled independently. Linear relationship between torque and current quadrature component Iqs made the control of induction similar to separately excited DC motor. Response was dynamically and instantaneous
