Guaranteed cost decentralized control for singular large-scale systems with parameter uncertainty
参数不确定广义大系统的保性能分散控制

The problem of guaranteed cost decentralized control for continuous-time singular large-scale systems with a quadratic cost function is considered.The system under discussions is subject to norm bounded time-invariant parameter uncertainty in all the matrices of model.The aim is to design a state feedback decentralized controller such that the closed-loop system is not only robustly stable but also guarantees an adequate level of performance for all admissible uncertainties.A sufficient condition for the existence of guaranteed cost decentralized controllers is also given in terms of linear matrix inequalities(LMIs) via linear matrix inequality approach.When this condition is feasible,the desired state feedback decentralized controller gain matrices can then be obtained.An illustrative example is also proposed to demonstrate the effectiveness of the proposed approach.
