Abstract:

 The decentralized output feedback global output tracking is studied for a class of large-scale nonlinear systems satisfying the Lipschitz condition. On the basis of recursive processing of given reference signals, time-varying decentralized output feedback trackers with two classes of design parameters are proposed. By choosing suitable values for the parameters, the proposed trackers can make the output of each subsystem globally exponentially track the corresponding reference signal. Finally, a simulation is given to demonstrate the effectiveness of the conclusion.

Key words: large-scale nonlinear system; decentralized output feedback; decentralized tracking control
