Robust H∞ Control for Stochastic Wind Power Generation Systems
This paper studies the design of robust H∞ controller for stochastic wind power generation systems. Assuming the system is convex uncertain，this article presents the H∞ performance criterion for uncertain stochastic system , deduces sufficiency conditions of the existence of H∞ controller with state feedback, and expresses them into a form of the linear matrix inequality (LMI), then utilizes schur complement lemma to transform them into LMIs which can be solved. At last we utilize standard digital software to get the disturbance attenuation level and the state feedback matrix.
