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...

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...

The L2–L∞ fuzzy control problem is considered for nonlinear stochastic Markov jump systems with neutral time-delays. By means of Takagi–Sugeno fuzzy models, the fuzzy controller systems and the overall closed-loop fuzzy dynamics are constructed. A sufficient condition is firstly...

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...

На основе метода размещения полюсов замкнутой системы в заданной области на комплексной плоскости и H∞-метода формирования контура с помощью аппарата линейных...
