Abstract :
It is known that linear multivariable minimum-phase systems with invertible high-frequency gain can be regulated by high-gain PI-controllers. An investigation is conducted to determine whether the stability of the closed-loop system is robust against perturbations induced by a class of measurement nonlinearities, including dead zones
