A HIGH-GAIN OBSERVER APPROACH APPLIED TO THE ROBUST FEEDBACK LINEARIZATION CONTROL

In this work the application of a high-gain observer approach to the robust feedback linearization control is proposed to control a class of nonlinear systems, which all states can not be measured. The robust feedback linearization technique is used to transform the nonlinear system into its linear approximation around an equilibrium and the high-gain observer to estimate the states of the system.
