This paper proposes a new control system for active mass dampers. The control system is a feedback system, which combines a single neural oscillator and a position controller. The output of the neural oscillator synchronized with the structure response is a rhythmic command which decides the driving direction of the auxiliary mass, and a special map plotted by periodic solutions of the oscillator determines the travel distance of the auxiliary mass in comparison with the current state of the neural oscillator affected by the structure response. In addition, in order to move the auxiliary mass to the desire value, the position control system consisting of a PD controller is used. As a result of numerical simulation, when the structure was quaked by the several types of the earthquake, the structural vibration was reduced by the effect of the auxiliary mass' motion, and the results showed that the proposed system was verified as the controller for the active mass dampers and was able to be used to solve the stroke limitation problem of the active mass dampers. |
