Robust global stabilization with ignored input dynamics: An input-to-state stability (ISS) small-gain approach
This note presents a redesign for global asymptotic stabilization in the presence of ignored input dynamics, restricted to be minimum-phase and relative degree zero. Using nonlinear small-gain arguments we design a static feedback control law to achieve global asymptotic stabilization. In the absence of full-state information, an observer-based stabilizing controller is proposed.
