Abstract :
A class of scheduled state feedback controllers are developed for disturbance attenuation in systems with bounded actuators. The scheduling parameter, obtained from a set of parameterized ellipsoids, is a measure of the system response and allows the controller to adjust to lower controller gains as the states become larger. The controller is obtained by approximating the desired parameter dependent variables with linear spline functions
