Abstract:
In this work a high-gain observer approach to be used with the robust feedback linearization control is proposed to control a class of nonlinear systems that contains parametric perturbation and for which all states can not be measured. The robust feedback linearization technique is used to transform the nonlinear system into a linearized system around an equilibrium and the high-gain observer to estimate the states that are not measured rejecting the perturbation.
