摘要
针对直流发电机组并联运行因输出电流不均而导致机组带负载能力下降等问题,提出采用自适应模糊PID控制方法实现对其进行均流控制。阐述了自适应模糊PID控制策略的基本原理,重点研究了采用自适应模糊PID控制实现发电机组并联均流的具体设计方法,并对其控制效果进行了仿真验证,同时与常规PID控制算法进行了对比仿真分析。结果表明:自适应模糊PID控制策略相对于常规PID控制算法具有响应速度快、超调量小、稳定时间短等特点,具有一定的应用价值。
The load capability of DC generator set in parallel operation decreases due to output current uneven distribution, current sharing for DC generator set based on self-adaptive fuzzy PID control method was presented. The basic principle of adaptive fuzzy PID control method was introduced. The design method of parallel current sharing for DC generator set using adaptive fuzzy PID control method was investigated, and the effect was verified with simulation. The results show that, relative to conventional PID control algorithm, adaptive fuzzy PID control algorithm has such qualities as fast response, small overshoot, stability in short time etc. , and it has a value for application.
