中文摘要	水轮机导叶开度的控制归结为一个复杂的非最小相位非线性控制模型,其自适应控制不易采用传统非线性控制方法解决。为解决水轮机导叶开度的自适应控制问题,将通用自适应输出反馈控制应用到水轮机导叶开度的控制。首先通过一个线性可逆变换将水轮机导叶开度控制的非线性模型变换成满足通用自适应输出反馈控制定理要求的形式,然后证明变换后的形式满足通用自适应输出反馈控制定理要求的条件,最后对变换后的模型应用通用自适应输出反馈控制定理得到相应的控制器。数值仿真表明,基于通用自适应输出反馈设计的水轮机导叶非线性开度控制是有效的,且对系统参数变化具有极强的鲁棒性。; Hydro-turbine generators sets’ governor control is described by a complicated non-minimum phase nonlinear model, to which traditional adaptive control methods cannot be easily applied. In order to give out a scheme for adaptive control of hydro-turbine generators sets’ governor, universal adaptive output feedback control method is applied to governor control of hydro-turbine generators sets. Firstly, the nonlinear model of governor control of hydro-turbine generator sets is transformed into the form whose structure satisfies the requirements from universal adaptive output feedback theorem (UAOFT). Secondly, it is proved that the mathematical characteristics of the transformed form for governor control of hydro-turbine generator sets satisfy the requirements from UAOFT. Finally, an adaptive nonlinear controller for governor control of hydro-turbine generator sets is gotten by UAOFT. Numerical simulations manifest that the adaptive nonlinear controller designed is effective, and it has strong robustness to system parameters’ variations.
