The finite-time H control of a fractional-order hydraulic turbine governing system (HTGS) is studied. First, a fractional-order HTGS as well as its generalized Takagi-Sugeno fuzzy model is presented. Then, based on the fractional-order stability theorem, the robust H state feedback control is designed to guarantee that the HTGS is asymptotically stable with prescribed H_∞ performance. Furthermore, the H_∞ control is integrated with finite-time control theory, a finite-time H_∞ control is proposed for the fractional-order HTGS, and the stability condition is given in terms of linear matrix inequalities. Finally, simulation results verify the validity and superiority of the proposed control method.
