| 摘 要： | 为提高天然气发电机组交流频率的控制精度,提出了基于规则修改和比例因子自调整的自适应模糊频率控制方法．自适应模糊控制器通过改变误差和误差变化的权值来修改控制规则,根据机组负荷区域及负荷变化采用模糊决策调整比例因子．试验结果证明了自适应模糊频率控制的有效性和可行性．

| Abstract: | To improve the precision of frequency control for natural gas engine generating set,a new fuzzy control scheme based on modifying fuzzy rules and self-adjusting scale factor was proposed. Fuzzy control rules are modified through changing the weighted value of error and error change. Scale factor is adjusted by fuzzy decision according to load and load change of the generating set. Experimental results demonstrated that this self-adapting fuzzy control scheme is valid and effective for frequency control. |
