针对现有电化工业电解槽极化电源主电路普遍采用晶闸管相控整流方案存在的不足,提出了采用交-直-交-直的新型主电路方案,并采用自适应模糊PID控制方法进行软件设计.阐述了电源系统方案的设计、系统主电路结构及工作原理、控制电路分析.重点研究了自适应模糊PID控制方法的基本原理及软件实现,并对其控制效果进行了建模和仿真分析,与常规PID控制算法进行了对比实验分析.结果表明:自适应模糊PID控制算法相比常规PID控制算法具有响应速度快、超调量小、稳定时间短、电源输出谐波少、静态和动态性能好等特点.具有良好的应用价值.
In view of the defects of the existing industrial electrolytic cell electrochemical polarization power main circuit which widely uses the thyristor phased rectification, the cross-straight-to pay-straight new main circuit scheme is proposed, and the adaptive fuzzy PID control method is adopted to improve the software design. In this paper, the design of the power system solutions, system main circuit structure and the working principle and control circuit analysis are elaborated. The basic principle of adaptive fuzzy PID control method and the software implementation are studied, The control effect is modeled and simulat is carried out. Conventional PID control algorithm for the experimental analysis, the adaptive fuzzy PID control algorithm has fast response, less overshoot and short stable time, less output power harmonic, good static and dynamic performance. It has good application value.
