Abstract :
In this paper, we propose a decentralized H∞ control design technique through approximation. We show that a decentralized H∞ control problem as well as any fixed structured H∞ control problem can be (conservatively) converted into a model approximation problem. We then propose some explicit parameterizations of the decentralized controllers and the final decentralized controllers are obtained through some convex optimization.
