摘要
针对水轮机调节系统结构复杂、难以控制等问题,在传统PID控制的基础上,运用模糊理论提出了基于模糊自适应PID控制的水轮机调速器参数整定方案,以实现对系统进行实时、在线控制。在水轮机调节系统数学模型的基础上,根据PID 3个参数分别对系统性能产生的影响,完成了模糊自适应PID控制器的设计与Matlab环境下的程序编写。在系统处于不同频率扰动下,分别采用提出的模糊自适应控制方案和Ziegler Nichols算法进行仿真实验。结果表明,提出的模糊自适应控制方案是一种有效的水轮机调速器参数整定方法,相比Ziegler Nichols算法,该方案控制下的系统能获得更好的动态性能。
It is known that the control of water turbine regulating system is difficulty since its complicated structure. On the basis of traditional PID control,a parameter control scheme of hydro turbine governor is proposed to realize the realtime and on-line adjustment of PID parameters for this system based on fuzzy adaptive PID control. According to the different influence on system performance produced by the three PID parameters,we have completed the design and programming of the fuzzy adaptive PID controller with Matlab based on the mathematical model of water turbine regulating system. The proposed fuzzy adaptive control scheme and Ziegler Nichols algorithm are simulated under different frequency disturbance. The experimental results show that the fuzzy adaptive control scheme is an effective parameter setting method for water turbine governor. This method makes the system obtain better dynamic performance compared with Ziegler Nichols algorithm.
