摘要: 针对磁耦合谐振式无线电能传输系统的频率失谐问题及现有谐振频率调节方式的弊端,提出一种基于模糊 神经网络 PI(proportional integral)控制的频率跟踪控制策略。为验证所提控制策略的有效性,使用 Matlab/ Simulink 仿真软件搭建系统模型,对所提控制策略进行仿真分析。 仿真结果表明:与传统 PI 控制及模糊 PI 控制相比,模糊神经网络 PI 控制的系统具有响应速度更快、调节时间更短的优势,且在系统受到干扰时, 超调量最小、调节时间最短,由此可看出其具有更好的抗干扰能力。

Abstract: Aiming at the frequency detuning problem of the magnetic coupling resonant wireless charging system and the shortcomings of existing resonance frequency adjustment methods, a resonant frequency tracking control strategy based on fuzzy neural network proportional integral (PI) control is proposed. Matlab/Simulink is used to build the system model, to simulate and analyze the proposed control strategy. Simulation results show that compared with the traditional PI control and fuzzy PI control, the fuzzy neural network PI control has the advantages of faster speed and shorter adjustment time for the system, and has smallest overshoot and shortest adjustment time under disturbance, which further verifies the effectiveness and better anti-interference ability of the proposed control strategy
