Robust Control for Uncertain Structural System Based on LMI

Abstract

This paper presents an active vibration control scheme for uncertain structural system. The state feedback controller is designed in term of Hinf robust control theory and the optimal solu- tion is obtained by using LMI convex optimal technique. A numerical example of three-degree-of- freedom system is taken to verify the proposed approach.The simulations demonstrate the effective- ness and feasibility.
