Exact Linearization And Robustness Analysis Of The Hydraulic Turbine Model

Differential geometry has been widely used in the theory of nonlinear control system.According to the nonlinear differential geometric control theory, this paper researches on thenature of the turbine governor system, proves water hammer effects model of Turbine governorsystem theoretically meet the conditions of state feedback precise, gives the exact linearizationprocess of the the turbine water hammer effects model. And derive the state feedback law of thissystem, achieve state feedback exact linearization of the original system. Use of MatLabsimulation for each variable were compared verify optimal results. Also the differentialgeometric control theory combined with SD feedback linearization method, in-depth study of therobustness of the system performance.In this paper, state feedback law is gained by usingdynamic method of dimensional, the stability of the zero dynamics is verified to evaluate thestability of the entire system, and also the robust control effect is verified by using MatLabsimulations.
