The proposed novel Large-scale systems formulation of decentralized adaptive tracking control strategy consists of a steady-state controller and a Tracking problem modified optimal feedback controller. Design parameters-dependent feasibility conditions are formulated by Adaptive dynamic programming using Lyapunov theory to guarantee the existence of our proposed decentralized control scheme.
