摘要
水轮机调节系统本质上是非线性的,特别对于导叶接力器反馈间隙所产生的极限环而言.本文提出了补偿校正办法以消除极限环的存在.通过大量计算,得出了非线性因素对系统动态特性影响的规律.
The hydraulic turbine governing system is substuntially nonlinear. In particular, the guide vane servomotor feedback backlash results in a limit cycle in the system. In this paper, a method of compensation and correction is presented to elimitate the limit cycle. Based on a large amount of computation, the regularity of the influence of nonlinear factors on the dynamic characteristics of the system is pointed out.
