Abstract

The influence of neglected dynamics appearing as multiplicative uncertainties on a closed-loop system with input and output saturations is studied. Constructive conditions based on (possibly linear) matrix inequalities, are provided in order to compute the influence of these beforehand neglected dynamics on both the estimate of the closed-loop system basin of attraction and the performance. The case of practical interest of neglected flexible modes and sensor dynamics is presented.
