| Título | A Distributed Dual Algorithm for Distributed MPC of Linear Dynamic Letworks | |
| Abstract: A linear dynamic network (LDN) is a system of interconnected subsystems that are coupled through dynamics and constraints, which can model geographically distributed systems such as urban traffic networks. For model predictive control (MPC) of LDNs, a distributed dual algorithm is proposed for optimizing control signals over a prediction horizon. While a master problem updates Lagrangian multipliers and penalty factors for the constraints, a slave problem is decomposed into a set of distributed subproblems whose variables are constrained only in sign. Under convexity assumptions, the distributed algorithm was shown to produce a sequence of iterates converging to the globally optimal solution. In an application to green-time control of an urban traffic network, the distributed algorithm yielded optimal solutions that corroborate the theoretical analysis. | ||
