Output strictly passive and input strictly passive of neutral systems

This paper concerns the problem of output strictly passive control and input strictly passive control for neutral systems. The aims at designing state feedback controllers so that the neutral systems are asymptotical and output or input strictly passive. In terms of a linear matrix inequality (LMI) and Lyapunov function, the strictly passive criteria is formulated. And the desired passive controller is given. Finally, a numerical example is given to demonstrate the effectiveness of the proposed approach.
