Communications for Coordinated Control via Covariance Management

Back
Abstract:
Interaction between coordinating systems requires communication of information between the systems. Our aim is to quantify the required level and content of this communication. In the example considered, the interaction is developed as a non-collision constraint between vehicles and each vehicle solves a constrained Model Predictive Control (MPC) problem to determine its path - with the non-collision constraint being central. The extension of MPC from a full-state feedback strategy to one involving state estimates allows the adoption of the estimate covariance as a means to manage the communication requirements. This, in turn, admits a formulation of the communication resource assignment problem as a set of coupled Linear Matrix Inequalities, which link the control objectives, the external disturbance, and the communications.
