Abstract :
This paper considers the design of a full order output feedback decentralized H∞ controller. An iterative algorithm that is based on the idea of two homotopy paths is proposed. Along one homotopy path, the decentralized control design problem, which is essentially non-convex, is locally linearized and solved. Along the other homotopy path the existing controller is deformed at each step so that in the end it attains a decentralized structure. A decentralized control design for a doubly inverted pendulum is demonstrated using the proposed algorithm.
