This paper mainly studies the problem of designing a non-fragile robust controller for a class of singular discrete non-linear systems with delayed state and uncertainties. Based on Lyapunov stability theory and linear matrix inequality (LMI), LMI-based sufficient condition for the singular discrete nonlinear systems to have robust performance is derived. The condition enables us to determine robust...
This paper addresses the problem of delay-dependent robust H∞ control for uncertain systems with state and input delays. By using the delay partitioning technique, an improved criterion is proposed for uncertain systems with state and input delays in terms of linear matrix inequalities (LMIs), which guarantees the time-delay systems satisfy a prescribed H∞ norm bound constraint for admissible uncertainties...
The problem of adaptive robust control for uncertain nonlinear systems with time-varying delay is considered in this paper. The upper bound of the uncertainty is assumed to be nonlinear functions with unknown coefficients. By using adaptive control method, a class of adaptive robust state feedback controller is proposed. Based on Lyapunov-Krasovskii method and Lyapunov stability theory, it is shown...
This paper considered robust Hinfin control for uncertain system with mode-dependent time delays and Markovian jump parameters. The problem aims at designing a state feedback controller so that the uncertain neutral systems are robust Hinfin stable. The estimating procedure is implemented by solving a linear matrix inequality (LMI). In terms of an LMI and Lyapunov function, the Hinfin stability criteria...
In this paper, robust Hinfin state feedback control problem is investigated using delta operator for discrete-time networks with state and input quantizations. A new model of network-based control with simultaneous consideration of network induced delays, data packet dropouts and measurement quantizations is proposed based on Lyapunov-Krasovskii functional in delta domain. The linear factional uncertainty...
The design of robust Hinfin controller for a class of uncertain neutral systems with varying state delay and input control delay is considered. The uncertainties are norm-bounded and the states of the uncertain neutral systems are available. Combining the linear matrix inequality with Lyapunov functions by proper assumption, the existent conditions of quadratic stabilization and Hinfin state feedback...
