This paper studies the problem of designing H∞ controllers for networked control systems
(NCSs) with both network-induced time delay and packet disordering. A delay switching-
based method is proposed to model the NCSs with long time delay as switched systems,
then by an algorithm involving convex optimisation, H∞ controllers are designed by using
the proposed delay switching-based method and the existing parameter uncertainty-based
method. Then, prediction-based method is presented to compensate time delay and packet …

The article is concerned with the design of H∞ controller for networked control systems
(NCSs) with both time delay and packet disordering. Analyzing and establishing the relation
between time delay and packet disordering, the NCS with both time delay and packet
disordering is transformed into the model with multi-step time delays. Given the time delays,
we can easily obtain the action time of the control signals without calculating the disorder
number. Moreover, a new notion of effective value of transmission packets (EVTP) is …
