Abstract :
It is well-known from linear systems theory that an integral control law is needed for asymptotic set-point regulation under parameter perturbations. The paper presents a similar result for a class of nonlinear systems in the presence of an unknown equilibrium due to uncertain nonlinearities and dynamic uncertainties. Both partial-state and output feedback cases are considered. A procedure for robust nonlinear integral controller design is presented and illustrated via a practical example of fan speed control
