A significant challenge of decentralized control is how to ensure global stability in large-scalinterconnected systems by local controllers that employ only local information, Since earlie1980s,decentralized adaptive control has motivated continued exploration and research of many researchers, However, in the presence ot uncertainties and strong interactions, the proposed schemes in this area have generally been limited to achieving stability only over alinfinite time horizon, with the elimination of steady-stateerrors posing a particular challenge.Decades of attemots to enhance the convergence rate of decentralized contro schemes have made little progress.

Recently, a methodology termed prescribed-time control emerged, demonstrating advantages in achieving accelerated convergence and superior disturbance reiection. The core innovation lies in an unbounded time-varving feedback gain,which enables precise control without prior disturbance knowledge and,crucially, allows for a convergence time that is preassignable by the designer.Building on this principle, we recently achieved a key breakthrough not only developed a decentralized prescribed-time control framework for strongly interconnected systems but also solved the long-standing problem of achieving precise control in such systems under disturbances. The details of the proposed approach and establishecresults will be covered in this talk.
