Pseudo-decentralized switching control

The decentralized control of plants with uncertain mathematical models is studied in this paper. In particular, it is assumed that the plant is described by a continuous LTI model, which is contained in a specified family P@? of plant models, and in this case it is assumed that a family of decentralized controllers has been found to satisfactorily control the models contained in P@?. A switching control scheme is then proposed that uses the input-output information of each agent to switch between the local candidate controllers in each corresponding agent. A binary communication link is assumed to exist between the local control agents to assure that all agents switch to the next candidate controller, simultaneously. Simulation results, using the proposed decentralized scheme, are given and compared with the centralized scheme.
