Switched Lyapunov Function based Controller Synthesis for Networked Control Systems: A Computationally Inexpensive Approach

This paper presents a Lyapunov function based control strategy for networked systems (NCS) affected by variable time delays and data loss. A special focus is put on the reduction of computational complexity. specific buffering mechanism defined first, such that it adds an additional delay up to one sampling period. The resulting buffered NCS can then be formulated as switched system which leads significant simplification model subsequent controller synthesis. novel approach does not only circumvent need any over-approximation technique, since used stability analysis directly, but also reduces infinite set allowable values dynamic matrix small finite set. proposed hereby strongly decreased number optimization variables linear inequalities (LMIs) allows greater flexibility with respect degrees freedom affecting transient behavior. performance efficiency are demonstrated means simulation example.
