摘要
根据PWM整流器在两相静止坐标系中的数学模型及瞬时功率理论,提出了一种瞬时功率预测方法,并结合模糊逻辑,改进了直接功率控制策略。该策略具有更好的动态性能,更快的响应速度。同时建立了基于MATLAB的PWM整流器仿真平台及研制了实验样机,通过仿真和实验结果验证了所提出的方法的可行性和有效性。
Based on instantaneous power theory and the mathematical model of the rectifier in two-phase stationary coordinate, a novel instantaneous power prediction method is proposed, and a direct power control strategy is improved by using fuzzy logic. The strategy has a better dynamic performance and faster response time. At the same time, a PWM rectifier simulation model based on MATLAB is established, and an experimental prototype is developed. The simulation and experimental results verify the feasibility and effectiveness of the proposed method.
