Robust Fuzzy Control for Fractional-Order Uncertain Hydroturbine Regulating System with Random Disturbances

Abstract EN

The robust fuzzy control for fractional-order hydroturbine regulating system is studied in this paper.

First, the more practical fractional-order hydroturbine regulating system with uncertain parameters and random disturbances is presented.

Then, on the basis of interval matrix theory and fractional-order stability theorem, a fuzzy control method is proposed for fractional-order hydroturbine regulating system, and the stability condition is expressed as a group of linear matrix inequalities.

Furthermore, the proposed method has good robustness which can process external random disturbances and uncertain parameters.

Finally, the validity and superiority are proved by the numerical simulations.
