摘要
水轮机调速系统,其控制对象具有不稳定零点,且结构复杂,难以建立精确模型,同时参数摄动和负荷扰动也很大。本文将2自由度控制和低敏感度法应用于水轮机调速器设计,设计出了能够克服模型化误差和参数及负荷度化的鲁棒调速器。仿真实验表明,这种调速器的鲁棒稳定性大大优于常规的PID控制器。
It is ditiieult to build the exact mathematical modei ot complicated hydraulic turbin SR system,which suffers large disturbance from parameters and loads. We apply two-degree-of-freedom control and low sensitive approach to hydraulic turbin SK system design. It overcomes the modelling errpr and the variations of parameters and loads. Simulating experiment shows that this robust govarner is better than conventional governor.
