In order to reduce physical burden of workers in industries, power‐assist devices (PADs) have been introduced. In many conventional PADs, the controlled objects are assumed as rigid bodies. This letter presents a vibration control method for power‐assisted moving vibration systems. The power assist is realized by an impedance control. If the impedance characteristics of the power‐assisted system are perfectly realized, they correspond to the disturbance dynamics for the vibration control. In this letter, we adopt the disturbance‐accommodating LQ optimal control method. A cart with a one‐degree‐of‐freedom vibration system is selected as a controlled object example. The effectiveness of the proposed method is verified by simulations. © 2011 Institute of Electrical Engineers of Japan. Published by John Wiley & Sons, Inc.
