Implementation of indirect field oriented control of a 2.2kW three-phase induction motor using MATLAB simulink

Abstract

Speed control of an induction motor using indirect field-oriented control (IFOC) method with space vector pulse width modulation (SVPWM) technique and proportional integral controller is presented and discussed in this paper. A 2.2kW three phase squirrel cage type Induction motor model with field-oriented control was simulated and analyzed using MATLAB/Simulink. The decoupling of the flux and torque producing components, for secondary control was carried out for the actual IFOC of the induction motor drive. The motor performance was analyzed under no-load, variable load, constant speed, and variable speed with load conditions. From the results obtained, the proposed control technique was found to produce satisfactory dynamic response and improved motor performance under these operating conditions.
