Abstract

Exact decentralized output-feedback Lyapunov-based designs of direct MRAC for linear interconnected systems with MIMO subsystems are introduced. The design process uses a coordinated decentralized structure of adaptive control with reference model coordination.We develop decentralized MRAC on the base of a priory information about only the local subsystems gain frequency matrices without additional a priory knowledge about the full system gain frequency matrix. To achieve a better adaptation performance we propose proportional, integral time-delayed adaptation laws. Copyright C 2005 IFAC.
