INDIRECT ROBUST TOTALLY DECENTRALIZED ADAPTIVE-CONTROL OF CONTINUOUS-TIME INTERCONNECTED SYSTEMS

This paper presents a global stability result on continuous-time indir ect totally decentralized adaptive control systems, The algorithms emp loyed in the design of local adaptive controllers are earlier basic co nventional adaptive control algorithms subject to parameter projection operation. For the first time, it is shown that without any restricti on on signals such as persistence of excitation, global boundedness of the signals in the overall continuous-time feedback system is guarant eed. For implementation, no a priori knowledge on the interactions and unmodeled dynamics is required.
