A Robust Design Method of Active Controller for Uncertain Vibration Systems

Abstract

This paper presents a robust design method of active controller for parameter uncertain vibration systems subjected to external unmeasurable disturbances. Based on the combination of complex modal theory, parameter optimization, linear matrix inequality approach, and robust eigenvalue assignment, the control law is reconstructed by adjusting the variable parameter r for robust active vibration control. The design is simple and easy to be implemented in real-time control.
