Abstract

The classic control theory does not take into account any physical limitation in communication networks when modeling the data transmission between plant and controllers or filters. Such phenomena can impact the system performance and even make it impossible to implement them, unless they are taken into account during the project. We aim to study such limitations and incorporate aspects from communication theory into control and filter design. Specifically, the study will focus on the packet dropout, constrained switching and transmission delay. In order to deal with packet dropouts, stochastic modeling of such transmission failures, based on Markov chains, can be incorporated into the Markov Jump Linear Systems framework. Considering the second subject, we seek to study switched systems where the transitions are not arbitrary, but depend on a known direct graph which informs which jumps between different modes are allowed. Finally, the transmission delays may be incorporated into the overall project, however, the system will be of infinite dimension. (AU)
