This paper investigates the finite-time consensus problem for double integrator multi-agent systems where each agent is subject to input saturation. The global leader-following consensus can be achieved in finite time over directed and detail-balanced communication topology under the proposed control protocol, which employs a priori saturation in order to deal with the constraints imposed on the control...
Stabilization problem for discrete-time switched systems with all unstable modes is investigated in this paper. Following the idea of getting into each unstable mode and analyzing its internal behavior, the state dynamical decomposition technique is used to convert such a problem to an equivalent one for the inter-decoupled switched systems. The proposed mode-dependent average dwell time approach...
This paper deals with the problem of L∞ adaptive control for a class of singular Lipschitz systems in the presence of both actuator saturation and actuator fault. To overcome the redundant design for fixed-gain controller where the same controller is used in both normal and fault cases, a fault tolerant controller with adaptive mechanism is developed to compensate the failure effects on systems with...
This paper deals with the controller design problem for Markovian jump systems subject to partial unknown transition probabilities and actuator saturation. Different from the previous results where complete knowledge on the transition probabilities is available, a new controller synthesis scheme is proposed as well as an estimate of the domain of attraction in mean square sense. A sufficient condition...
Solving state feedback Hinfin control problem usually leads to controller gain too large. A effective method to solve the problem is simultaneously to introduce guaranteed cost control. The delay-dependent Hinfin -guaranteed cost control problem for linear systems with state delay is investigated. A delay-dependent condition for the existence of Hinfin and guaranteed cost memoryless state feedback...
For switched system composed of linear subsystems with time-delay, the problem of Hinfin control is investigated. Based on quadratic Lyapunov function technology, a delay-independent condition for the problem of optimization of Hinfin performance to be solvable is derived by using Lyapunov-Razumikhin functional approach. Furthermore, a switching state feedback strategy is proposed to solve the Hinfin...
This paper deals with the problem of the guaranteed cost control for linear time-delay systems with input constraints. Firstly, the system is analyzed using Razumikhin functional approach which ensures that the closed-loop system with the designed controller is asymptotically stable and the cost function is no more than a specified upper bound for the input constraints. Secondly, based on the linear...
In this paper a new feedback structure, dynamic output feedback (dynamic compensator) plus state feedback, is utilized to stabilize rectangular descriptor systems. A necessary and sufficient condition is derived such that the resultant closed-loop system is regular, impulse-free and stable (it is called admissible). In addition, it is shown that, using this type compensator, the admissible condition...
