智能自整定水轮机调速器PID参数

Intelligent Self-Setting of PID Parameters for Hydro-Turbine Governor

叙述了离散水轮机调节系统 PID参数的预整定算法。设计了一个模糊自整定PID控制器 ,对水轮发电机组进行控制 ,利用模糊推理方式来实现 PID参数的在线调整 ,实现参数的优化。仿真结果表明 ,模糊自整定 PID的控制效果优于常规 PID控制。

The pre-setting method for PID parameters of the discrete governning system used in hydro-turbine is analyzed at first in this paper. A fuzzy logic self-setting PID controller is designed to control the hydroelectric generation unit. The PID parameters are on-line optimized and set by fuzzy logic reasoning.Simulation results show that the newly designed PID controller is better than routine one.
