摘　　要：针对水轮机调节系统的非线性、时变性及大惯性等特点,建立了其较为精确的数学模型,研究了模糊控制的基本原理,在此基础上构建了水轮机调节系统的模糊PID控制模型,并设计了适合水轮发电机组的模糊控制器,最后利用Matlab软件做了深入细致的仿真研究。研究表明,与常规的PID控制算法相比,引入模糊PID控制的水轮发电机组的调节特性得到了明显改善,并具有良好的动态品质。Aiming at the nonlinear, time variable and great inertia characteristics of hydraulic turbine regulation system, a precise mathematical model is built to study the basic principles of fuzzy control and fuzzy control algorithm in the paper. Based on this, the fuzzy PID control model of hydraulic turbine regulation system is constructed and fuzzy controller suitable for hydro generating set is designed. Finally, the simulation is done using Matlab. The research shows that compared with conventional PID control algorithm, the regulation characteristics of hydro-generating unit with the introduction of fuzzy PID control are improved remarkably and has a good dynamic quality.
