Filter Design for Continuous-Time Linear Systems Subject to Sensor Saturation

Abstract EN

This paper presents new sufficient conditions to cope with the filtering problem for continuous-time linear systems subject to sensor saturation.

A generalized sector condition has been used to handle the saturation in the measured output.

The H∞ performance was considered and a quadratic Lyapunov function was employed in order to derive the design conditions.

The conditions are presented in terms of matrix inequalities that become linear when a scalar parameter is fixed.

The efficiency of the proposed conditions and their capability to deal with different levels of saturation are illustrated by numerical examples.
