A Fixed-Frequency Optimization of PWM Current Controller-Modeling and Design of Control Parameters

Abstract : Design and modeling of the control parameters are important to guarantee the operation in a desired regime and to have the optimal dynamic behavior. To achieve these objectives, a proposed continuous-time averaging model is developed for a pulsewidth modulation current controller based on a modulated hysteresis controller while ensuring a fixed frequency operation. Stability analysis is performed using the eigenvalues of the system and estimating the bifurcation point for different cases to investigate parameter tuning. Moreover, the dynamic and static behaviors of the current for different values of bifurcation parameter are presented. The current controller in a two-loop control scheme is investigated. The simulation and experimental results are given to confirm the proposed method.
