This paper presents the design of double closed-loop security control structure. This structure is divided into two parts. First of all, sensor-controller-actuator loop completes the transmission of control signal output and measurement signal feedback. During the transmission process, the effects of uncertainties, perturbations, faults and attacks are coupled. Further, controller-detector loop is...
Since dynamic economic dispatch with wind power uncertainty plays an important role in power system operation, this paper proposes a fuzzy satisfying method based differential evolution with flexible interval selection mechanism. Sequential quadratic programming is embedded into differential evolution to provide optimal search direction for mutation operator. Fuzzy satisfying method with flexible...
This paper investigates robust stability analysis and stabilization of delay and uncertain systems approximated by a Takagi-Sugeno (T-S) fuzzy model. An innovative approach is proposed to develop delay-dependent stability criteria of the systems, which makes use of less-redundant information to construct Lyapunov function, employs an integral equation method to handle the cross-product terms, and...
This paper is concerned with a delayed feedback control design for uncertain systems with time-varying input delay. Based on a reduction method, a new control design method is proposed by introducing some relaxation matrices and turning parameters, which can be chosen properly to lead to a less conservative result. A numerical example is given to show the effectiveness and less conservativeness of...
