Abstract
An H-infinity-based Lyapunov proof is provided for a result recently e stablished by Lin and Saberi: if a linear system is asymptotically nul l controllable with bounded controls then, when subject to input satur ation, it is semi-globally stabilizable by linear state feedback. A ne w result is that if the system is also detectable then it is semi-glob al stabilizable by completely linear output feedback. Further, an exte nsion which relaxes the requirements on the input characteristic is ob tained.
