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.
