Abstract

Information sharing among local controllers is the key feature of any Distributed Model Predictive Control (DMPC) strategy. This paper addresses the problem of communication failures in DMPC strategies and proposes a distributed solution to cope with them. The proposal consists in an information-exchange protocol that is based on distributed projection dynamics. By applying this protocol as a complementary plug-in to a DMPC strategy, the controllers become resilient against communication failures and relax the communication requirements. Furthermore, a discussion on the selection criteria of the information-sharing network and a reconfiguration algorithm, which is a contingency procedure to maintain the connectivity of the network, are also presented. In order to demonstrate the performance and advantages when adopting the proposed approach, a case study of a power-network control problem is considered.
