As the integration of a doubly fed induction generator (DFIG)-based wind power generation into power systems tends to increase significantly, the contribution of DFIG wind turbine is highly expected. Since the active and reactive power outputs of DFIG can be independently modulated, the...

This paper considers the problem of designing an H∞ fuzzy controller for a class of nonlinear systems with pole placement constraints. Based on an LMI approach, we develop a state-feedback controller that guarantees the L2-gain of the mapping from the exogenous input noise to the regulated...

In this paper we present sufficient conditions for global optimality of non-convex quadratic programs involving linear matrix inequality (LMI) constraints. Our approach makes use of the concept of a quadratic subgradient. We develop optimality conditions for quadratic programs with LMI...

In this paper, the design method of H∞ filter for a class of neutral delay-differential systems is investigated. A linear matrix inequality (LMI) approach is proposed to design a robust H∞ filter such that the filtering system remains asymptotically stable and the bound of H∞ norm is...
