Nonlinear adaptive decentralized stabilizing control for the hydraulic turbines´ governor system

This work develops a design approach to nonlinear adaptive decentralized control system with unknown parame-and applies it to hydraulic turbine´s governors control. The adaptive control strategy is formed by the adaptive back-stepping way without involving transformation of linearization. The characteristic of the controller is that which involves a dynamic estimator of parameters. A general expression of nonlinear adaptive decentralized governors control strategy is acquired, in which all of the feedback variables are local measurements. Simulation results on a one-machine-infinite-bus system manifest the validity of the nonlinear adaptive controllers.
