Abstract :

This paper proposes mixed eigenstructure assignment with H∞ constraint when the states are not measurable. In this case, full state feedback is not permissible. So eigenstructure assignment by output feedback is considered. According to enhanced linear matrix inequality (LMI) and parametric eigenstructure assignment, we propose a method in terms of linear matrix inequality (LMI). This LMI can be easily solved by the Yalmip or LMI toolbox.
