Considering the uncertain time-delay of networked control systems, the networked control systems is modeled as an uncertain discrete system with delay firstly, using Stability theory of Lyapunov and linear matrix inequality approach, discussed the system stability. Combining with a given quadratic performance index, a necessary and sufficient condition for the existence of guaranteed performance controls...
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...
This paper presents a new stability result for discrete time-delay systems with additive delays. This approach has a strong application background in networked control systems. The stability criterion is expressed in the form of linear matrix inequalities, which can be readily solved by using standard numerical software. An illustrative example is provided to show the advantage of the proposed result.
To solve the stability control problem of Networked Control Systems (NCS) with time delay, a new method of building a discrete fuzzy T-S model is proposed for NCS generalized plant, and the model is proved theoretically to be able to approach a real plant at an arbitrary precision. Based on the fuzzy T-S model, the sufficient stable condition of the fuzzy controller independent of time delay is deduced...
