摘要：

Vibration control has attracted much attention nowadays, and the vibration-suppressed system has brought people many profits. This paper presents a new method for disturbance rejection control using optimal derivative feedback, which is aimed at vibration damping of linear, continuous, time-invariant system. We combine the theory of disturbance rejection control and the theory of optimal derivative feed-back control to yield a new active vibration control theory so that disturbance rejection control using acceleration or velocity feedback directly becomes possible. The frequency of the disturbance is supposed to be fixed and the feedback gain is derived by solving Lyapunov function iteratively. The paper first introduces the modelling of system and the optimal control algorithm. Then, simulations based on MATLAB are conducted and the proposed theory is verified. From the simulation results we can draw the conclusion that the proposed algorithm is efficient in disturbance rejection control.
