Rotor Flux Oriented Control of 3- \(\Phi \) Induction Motor
摘要
This chapter presents an in-depth study of Rotor Flux Oriented Control (RFOC) applied to 3- \(\Phi \) induction motors (IM). RFOC offers superior dynamic performance compared to traditional scalar control methods, particularly in decoupling torque and flux control. The chapter covers the theoretical foundation of RFOC, beginning with the Park transformation and its application to the motor’s voltage and flux equations. It then provides details on the implementation of RFOC using current-controlled and voltage-controlled PWM techniques. Several control loops for speed, torque, and flux are explained, along with their respective controllers and estimators. The chapter also includes extensive simulations carried out using MATLAB/Simulink, where a detailed model of the induction motor and the control strategy was implemented. The simulation results demonstrate the effectiveness of RFOC in both steady-state and dynamic conditions, validating the robustness of this control method in decoupling the control of torque and flux while maintaining precise performance under varying load conditions.
