This paper deals with the reliable control for uncertain singular systems with time-varying delay. Based on integral inequality, an linear matrix inequality (LMI) approach is developed to design desired state feedback controllers, such that the closed-loop system is regular, impulse free and stable for all admissible actuator failures. All the obtained results are formulated by strict LMI involving...
This article investigates the exponential stable guaranteed cost control problem for a class of uncertain neutral type systems with time-delay. Based on the Lyapunov second method, the linear memoryless state feedback control laws are designed such that the closed-loop system is exponentially stable and the closed-loop cost function value is not more than a specified upper bound for all admissible...
An observer-based robust predictive control algorithm for singular systems with convex polytopic uncertainties is presented by linear matrix inequality formulation. By constructing the Lyapunov function with the error term, the infinite time domain dasiamin-maxpsila optimization problems are converted into linear programming problems, the sufficient conditions for the existence of observer-based robust...
This paper investigates the problem of output feedback robust Hinfin controller design for sampled-data systems with time-varying norm-bounded parameter uncertainties in the state matrix and input matrix. Attention is focused on the design of a causal output feedback sampled-data controller which guarantees the asymptotical stability of the closed-loop system and reduces the effect of the disturbance...
This study deals with guaranteed cost control problem for discrete time nonlinear systems with parameter uncertainties. The Takagi and Sugeno (T-S) fuzzy model with parameter uncertainties is employed to represent an uncertain discrete time nonlinear system. Based on the structural information in rule base, a piecewise output feedback controller design method is introduced. Sufficient condition for...
This paper investigates the problem of delay-dependent robust Hinfin control for uncertain singular systems with time-varying state delay. The considered systems are not necessarily assumed to be regular and causal. In terms of linear matrix inequality (LMI)approach, a delay-dependent stabilizable criterion is given to ensure the nominal system to be regular, impulse-free and stable. Based on the...
A special guaranteed cost control problem is studied for a class of uncertain time-delay singular systems. Firstly, the system is transformed to an auxiliary system equipped with disturbance input, by regarding the parametric uncertainties as disturbance input. Then, sufficient conditions are presented, which not only make the closed-loop system regular, impulse free and asymptotically stable for...
This paper addresses the problem of designing the state feedback tracking guaranteed cost controller for a class of norm bounded continuous-time uncertain systems. Firstly, the approach to design a state feedback guaranteed cost controller is presented. The closed-loop system with the designed controller is asymptotically stable and the closed-loop cost function value is not more than a specified...
This paper deals with the design problem of adaptive robust reliable control for uncertain time-delay systems with actuator failures. A more practical model of actuator failures characterized by the average factor and the failure degree is adopted. A sufficient criterion for the existence of the adaptive robust reliable controller is derived in linear matrix inequality (LMI) framework and a design...
