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.
