This note deals with observer design for nonlinear systems. The main contribution of this work consists in providing a new high-gain observer design method with lower gain compared to the standard high-gain observer. This new observer, called HG/LMI observer is obtained by combining the standard high-gain methodology with the LPVLMI-based technique. We will show through analytical developments how the new observer provides a lower gain. A numerical example is given to illustrate the performance of the new HG/LMI observer.
