Advanced Control Systems Optimization

Abstract The concept of absolute tracking (Grujić and Porter 1980) is extended so as to embraco Lur´e control systems subjected to multiple immeasurable disturbances and multiple unmeasurable command inputs. It is shown that the tracking characteristics of closed-loop control systems incorporating Lur'e plants with multiple 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 Lur'e plant with two non-linearities.
