A class of networked control systems is investigated where the plant has time-varying norm-bounded parameter uncertainties, both the sensor-to-controller and controller-to-actuator channels implement multiple-packet transmission and experience random packet dropouts. Sufficient conditions for synthesis of robust stochastic stabilisation and design of robust(More)

We consider the stability of the discrete-time networked control systems (NCSs) with polytopic uncertainty, where a smart controller is updated with the buffered sensor information at stochastic intervals and the amount of the buffered data received by the controller under the buffer capacity constraint is also random. We establish sufficient conditions for(More)
In this contribution, we investigate a class of observer-based discrete-time networked control systems (NCSs) with random packet dropouts occurring independently in both the sensor-to-controller (S/C) and controller-to-actuator (C/A) channels. We first propose and prove a separation principle for the general class of NCSs where packet dropouts in the C/A(More)
A general class of model-based networked control systems is investigated where the plant has time-varying norm-bounded parameter uncertainties and both the sensor-tocontroller and controller-to-actuator channels experience random packet dropouts. Sufficient conditions for guaranteeing the robust stochastic stability and synthesis of stabilisation controller(More)
This paper considers analysis and synthesis of discrete-time networked control systems (NCSs), where the plant has additive uncertainty and the controller is updated with the sensor information at stochastic time intervals. It is shown that the problem is linked to robust control of linear discrete-time stochastic systems and a new small gain theorem is(More)
We consider a class of networked control systems (NCSs) where the plant has time-varying norm-bounded parameter uncertainties, the network only provides a limited number of simultaneous accesses for the sensors and actuators, and the packet dropouts occur randomly in the network. For this class of NCSs with uncertainties and access constraints as well as(More)
Stability of the discrete-time networked control systems is analysed, where the controller is updated with the buffered sensor information at stochastic intervals and the amount of the buffered data for transmission under the buffer capacity constraint is time-varying. The adopted controller switches between open-loop and closed-loop modes to estimate the(More)
