This paper considers the nonlinear surface design for uncertain discrete time system with state delay. Using Lyapunov-Krasovskii method delay-independent conditions are derived for the stable sliding motion along the nonlinear sliding surface. The sliding surface is typically designed to obtain the high speed response without exhibiting the overshoot. This can be achieved by keeping the damping ratio...
This paper presents the method of discrete-time sliding mode control (DT-SMC) for a class of nonlinear time-delay systems via Takagi-Sugeno (T-S) fuzzy model. First, the discrete-time linear model with uncertainties and tine-varying delay is derived by employing T-S model to represent original system. Then the control problem becomes the robust stabilization controller design for linear uncertain...
A delay-dependent sliding mode control algorithm for the networked control system (NCS) with mismatched uncertainties and stochastic less delay is studied. Considering stochastic less delay of the NCS, delay estimation online is present. The delay iterative measuring and pretest parameters-based estimation methods are adopted. Loop delay estimation online is designed to overcome the adverse influence...
The delay-dependent sliding mode control problem of a class of uncertain neutral delay systems is considered. By selecting a sliding surface depending on the current state and delayed state, the paper gives a delay-dependent sufficient condition in terms of linear matrix inequalities(LMIs) such that the closed-loop system is guaranteed to be asymptotically stable. According to reaching condition,...
