| 摘 要： | 针对常规P ID或模糊控制对非线性、时变、高阶水轮发电机组系统不能达到较好控制效果的问题,提出一种模糊和P ID复合控制策略,并对模糊和P ID控制结合形式进行了详细讨论。结合水轮发电机组模型,采用专家经验和遗传算法优化相结合的方法对每种模糊和P ID结合形式进行了参数和规则整定,并对各种复合控制策略进行了仿真实验,分析了模糊和P ID如何优势互补达到较好的控制效果。

| Abstract: | Conventional PID or fuzzy controller can't achieve satisfactory control performance on hydroelectric generating unit control,which is a non-linear,time-varying,and high-order system.In order to overcome the shortcoming of conventional controller,fuzzy-PID composite control method is proposed.The combining modes of fuzzy and PID controllers are discussed in detail.Based on the model of hydroelectric generating unit,parameters and reasoning rules of every combining mode are tuned using expert knowledge and genetic algorithm.Each control strategy is simulated and the response curves which reflect the control effect are given.On the basis of simulating experiment,the way to improve control effect is analyzed. |
