A decentralized feedback stable controller was given for a class of linear time varying large scale systems, which are nonlinear interconnected and uncertain. This controller has strong robustness. When the uncertain bounds are unknown, the designed controller by using estimated bounds either is excessively conservative or make the system unstable, and the nonlinear controller only can make the system practically stable. But the introduction of dynamic states feedback controller avoids the these shortages. Finally, simulations show that the results are effective.
