锅炉汽包水位控制系统是火力发电厂中的一个重要的热工控制系统，汽包水位的
控制大多采用传统PID控制方式。但是，传统PID控制器参数的整定是在获取对象数学
模型的基础上，根据某一整定规则来确定的，不能进行在线调整，难以适应锅炉汽包
水位这样一个复杂多变的控制系统，其控制效果往往难以满足要求。
本文应用模糊控制技术，设计了一种二输入三输出模糊自整定PID控制器，对锅
炉汽包水位进行控制，实现了PID参数的自适应调节。利用MATLAB对控制系统进行
仿真。结果表明，该控制器自整

本论文对国内外光电式电流互感器的供能方式进行了总结，论述了其优缺点。其中，基于超声波供能的光电式电流互感器是目前的最新研究成果，目前的研究已经验证了其可行性，但是存在传输效率低的严重问题。超声波供能系统的研究，需要大量的力学实验，不便于实现。本论文通过对力学中超声波的波动方程进行推导，寻找出了一组和电学中传输线方程相类似的方程组。通过对比电学和力学中的物理量，得到了它们之间的对应关系。在此基础上，构建出了超声波传能装置的等效电路模型，并进行了仿真实验。通过在电学中的仿真结果，较为直观的反应出了超
