Further result on decentralized stabilization via saturated delayed feedback

This paper investigates the decentralized stabilization of large scale feedforward nonlinear systems via saturated delayed feedback. A class of saturated delayed controllers is first proposed for the single-input feedforward nonlinear systems: an appropriate normal form rather than the homogeneous property of feedforward systems is depended on, and a small parameter contained in the normal form is assigned into the control law. By tuning the small parameter, the control design allows an arbitrarily large input delay. This scheme is then extended to the setting of decentralized feedforward nonlinear systems. The effectiveness of the suggested algorithm is verified by simulations.
