Abstract:
Predictive current control techniques rely on the accuracy of flux angle detection, which seriously impacts the control performances for induction motor drives. Aiming at this, many researches have been proposed to improve the flux angle detection accuracy, which usually complicates the system design and algorithm realization. In this work, we propose an effective and simple predictive power control strategy for induction motors that omits flux angle detection and simplifies the system design. Similar to classical predictive torque control, the proposal does not require flux angle information. Moreover, it requires no weighting factor design process. In addition, a stable flux observer in the stationary coordinate system is proposed and the conditions to satisfy Lyapunov stability are detailed. The effectiveness of this work is verified by experimental data. Compared with the classic predictive control strategies, the proposed method shows superior steady and dynamic performances with a simplified control structure and realization.
