Abstract :
An H∞-based Lyapunov proof is provided for a result recently established by Lin and Saberi (1993): if a linear system is asymptotically controllable with bounded controls then, subject to input saturation, it is semi-globally stabilizable by linear state feedback. A new result is that, if the system is detectable, it is semi-global stabilizable by completely linear output feedback. Further, an extension which relaxes the requirements on the input characteristic is obtained.
