On decentralised output feedback control of a class of composite systems with delay interconnections and uncertainties

The stabilisation control for a class of composite plants based on the concept of output feedback is investigated. A decentralised control is constructed to stabilise this class of large-scale systems with delay and time varying uncertainties in the interconnections. The control action is based on the output feedback. Interconnections satisfy the so-called matching conditions. A sufficient condition is presented, which ensures uniform ultimate boundedness for both the subsystems and the overall system.
