The Control System for Three-Phase Induction Motors Based on Stator Flux Orientation

Abstract:

In this paper, the mathematical model of induction motor based on stator field orientation in synchronous frame is introduced. To resolve the question of relay, the d-axis current direct calculation is adopted to replace traditional decoupler. Fix threshold double-integrator based on coordinate transformation is used to eliminate integrator saturation. SVPWM based on 60⁰ coordinate system is developed to simplify calculation. The control system based on stator flux orientation is simulated by MATLAB. The simulation result shows that the system has a fast dynamic response and steady characteristics.Nomenclature
