Resumo

This paper presents a proposal of a robust output feedback controller to perform reference tracking, ensuring that the system complies with the constraints despite the effect of bounded disturbances and parameter uncertainties. The proposed technique is based on the calculation of invariant sets to ensure constraints satisfaction and a model update to reduce the tracking error of constant reference, through a system of inequalities. The numerical simulation results illustrate the efficiency of the proposed method.
