Packet-Based Networked Control Systems in Continuous Time

Abstract

In all the previous chapters (Chaps. 2, 3, and 4) the packet-based control approach is considered for plants in discrete time and discrete network-induced delay. The packet-based control approach is extended to the continuous time case in this chapter, with the use of a discretization technique for the continuous network-induced delay. The derived approach leads to a novel model for NCSs in continuous time. This model, as in the discrete time case, offers the designer the freedom of designing different controllers with respect to specific network conditions, which is distinct from previously reported results and results in a better performance. By applying switched system theory, the stability criterion for the derived model is obtained, which is then used to obtain an LMI-based stabilized controller for the continuous-time PBNCSs.
