为了在无线电能传输系统中获得恒定的输出电压,提出了一种基于模糊逻辑的电容阵列恒压控制方法.通过数学分析与理论推导建立了输出电压与等效电容值的关系式,以输出电压为控制对象,通过控制电容阵列的等效电容实现系统输出电压的恒定.在MATLAB/Simulink中建立了基于模糊逻辑的输出电压控制仿真模型,仿真结果证明了该控制方法的正确性.
In order to obtain a constant output voltage in the process of the wireless power transmission system,the paper presents a fuzzy logic constant control methods based on capacitive array.Through mathematical analysis and theoretical derivation to establish the relationships of the equivalent capacitance and the value of the output voltage,it takes the output voltage as the control object to achieve constant output voltage by controlling the equivalent capacitance of the capacitor array.The paper builds the fuzzy control sim ulation model in MATLAB/Simulink based on the control method,the simulation results prove the validity of the control method.
