摘　　要：温差发电系统在非均匀温度分布环境下工作时,会出现多个最大功率点,而在此环境下传统的电导增量法追踪效果差,输出功率波动大。针对此问题,该文先研究温差发电系统的输出特性,提出一种基于模糊控制的最大功率点追踪办法,建立MATLAB/Simulink仿真电路,并在相同环境下对2种算法进行仿真对比,实验结果表明模糊控制算法在非均匀温度分布环境下能快速、平稳、准确地追踪到最大功率点,提高温差发电系统的输出功率。There are many maximum power points in the temperature difference power generation system when it works in non-uniform temperature distribution environment.In order to solve this problem,this paper first studies the output characteristics of temperature difference power generation system,puts forward a Maximum power point tracking method based on fuzzy control,and establishes an MATLAB/Simulink simulation circuit,and simulates and compares the two algorithms in the same environment.Experimental results show that the fuzzy control algorithm can track the maximum power point quickly,smoothly and accurately in a non-uniform temperature distribution environment,and improves the output power of the thermoelectric power generation system.
