Abstract :
The H∞ disturbance rejection problem for a family of linear systems subject to control input constraints is considered. A class of controllers generalizing the standard Riccati equation-based state feedback is proposed and an estimate of their domain of validity is derived. A simple criterion for tuning controller parameters for validity domain maximization and local performance improvement is presented.
