Continuous-time tracking systems incorporating Lur'e plants with single non-linearities

Abstract

The concept of absolute tracking is introduced for Lur'e control systems subjected to immeasurable disturbances and immeasurable command inputs. It is shown that the tracking characteristics of closed-loop control systems incorporating Lur'e plants with single non-linearities can be established on the basis of the absolute stability characteristics of associated free systems. These general results are illustrated by synthesizing a tracking system incorporating a simple Lur'e plant.
