In this paper, based on Lyapunov function and linear matrix inequality (LMI) method, the problem of guaranteed cost control for a class of uncertain singular time-delayed systems with nonlinear perturbation is addressed. The sufficient conditions of non-fragile guaranteed cost control and corresponding controller design methods are presented.
This paper deals with a design problem of robust controllers for polytopic uncertain systems. The proposed design method is based on computation of the trajectory for the uncertain system and differs from the existing methods based on quadratic stabilization via Lyapunov criterion. In this paper, we show that sufficient conditions for asymptotical stability of the polytopic uncertain system and a...
According to the nonlinear closed electro-hydraulic proportional system, a multiple sliding mode adaptive control method is proposed. Recursive technique is used to simplify the control problem of higher-order system. A robust adaptation scheme was used to reduce the tracking error resulted from system uncertainties . Firstly, the recursive technique and state feedback precise linearization scheme...
The design approach of robust Hinfin controller for network control system (NCS) with random time-delay is studied in this paper. The model problem is discussed firstly. With time-driven sensor and event-driven controller and actuator, supposing that the time-delay is less than one sampling period, the NCS is modeled as an uncertain discrete linear system with delay, based on the Lyapunov functional...
