Abstract :
The paper addresses a problem of design of distributed robust filters using the dissipativity theory of distributed systems. The main result is a sufficient condition which guarantees a suboptimal H∞ level of disagreement of estimates in a network of estimators. The condition is formulated in terms of feasibility of certain linear matrix inequalities (LMIs). It is shown using an example that the proposed approach leads to an improved consensus performance.
