چکیده
in this paper, the problem of decentralized model reference adaptive control (mrac) for a class of large scale systems with time varying delay in interconnected term and input and state delays is studied. to compensate the effect of input delay indirectly, a smith predictor built on. to handle the effects of the time delays in input, the adaptive controller part includes two auxiliary dynamic filters with time varying gains. under a usual assumption that the interconnections are assumed to be lipschitz in its variables and uniformly in time with unknown lipschitz gains, the difficulties from unknown interconnections are dealt. a generalized error is defined and by a suitable lyapunov function, an adaptive controller is designed to stabilize it. decentralized adaptive feedback controller can render the generalized error system uniformly ultimately bounded stable is designed. finally, a numerical example is given to demonstrate the feasibility and effectiveness of the proposed design techniques.
