Decentralized control with information structure constraints

In this paper, some problems related to the design of decentralized controllers are considered. Due to information structure constraints on the systems, we are interested in determine when a gain-matrix corresponding to a control law can be designed having a required structure. To discuss this issue, we consider some generic classes of systems with different control strategies: optimal overlapping control, guaranteed cost control and H∞ control. For each one of them, two scenarios are supposed: state feedback and output feedback controllers. In this line, some new contributions are offered
