Resumen: In this work, we develop a new distributed output-feedback stochastic model-predictive control (SMPC) proposal for a plant that is cooperatively regulated by a set of actuator nodes. Contrary to most approaches, we consider hard constraints on the actuators, and we appropriately tighten the constraints to ensure recursive feasibility with a given probability, despite the stochastic noise present in the system. To lighten the communication load, the constraint design is performed offline, and an event-triggering mechanism is included, so that the nodes only need to transmit their local state estimates to neighbors at event instants during online execution. We prove constraint satisfaction and stability of our proposal, and we include simulation results showing that similar control performance to the centralized case can be achieved by our distributed SMPC with reduced communication.
