Decentralized Adaptive Output Feedback Control of Exponentially Practical Stability of Similar Composite Systems with Unknown Bounds of Uncertainties

The problem of adaptive output feedback controllers which exponentially practically stabilize a class of composite systems was considered. The systems are similar composite systems with uncertainties and disturbances. The conditions of output feedback controllers which exponentially practically stabilize systems were given. The uncertainties of the system can be nonlinear or time varying. The bounds of the uncertainties exist, but are unknown. A kind of certain nonlinear controllers which guarantee that the states of the system exponentially converge to the equilibrium's nearby region were designed. The simulations show the validity of the controllers design.
