INTELLIGENT NONLINEAR PID CONTROL OF HYDRO-TURBINE GOVERNORS
Author(s): 
Pages: 28-31
Year: Issue:  3
Journal: HYDROPOWER AUTOMATION AND DAM MORNITORING

Keyword:  PID算法非线性控制智能控制水轮机调速器;
Abstract: 将PID控制、非线性控制、仿人智能控制相结合,提出了一种智能非线性PID控制器,并讨论了其结构和算法.它在大误差时采用强比例、弱积分,小误差时采用弱比例、强积分控制,具有参数自适应和结构自组织的特点.对水轮机控制系统的仿真,智能非线性PID控制器具有响应速度快、超调量小的特点,可有效地改善水轮机调速系统的动态性能和鲁棒性.由于所述控制器的参数调谐和控制策略切换是基于控制误差进行的,因此易于在工程实践中实施.
