The Design of Decentralized Robust Tracking Controllers for Large-Scale Uncertain Systems with Time-Delay
不确定性时滞大系统的分散鲁棒跟踪控制器设计(英文)

This paper is to study the decentralized robust tracking control problem for large scale uncertain systems with time delay. The uncertainty is value bounded and can not satisfy its matching conditions. A sufficient condition for the existence of decentralized robust tracking controller is derived. This condition is expressed as the solvability problem of linear matrix inequalities (LMIs). Based on that, a convex optimization problem with LMI constraints is formulated to design a decentralized state feedback control with smaller gain parameters which enables the controlled system to approach the reference input asymptotically.
