Vibration control of a structure using an active mass damper operated by neural oscillator and position controller

(A design method of PD gains based on an eigen-frequency and damping ratio of position control systems)

Abstract

This paper proposes a new design method of a position control system (PD controller) for active mass damper systems including neural oscillators. Our previous system provided rectangular desired values for the auxiliary mass of active mass damper in the neural system. Due to the rectangle shape, the AMD system generated appreciable acceleration as the direction of motion of the auxiliary mass changed during operation. In order to reduce the impulsive acceleration, a new neural system, which could generate smooth desired values, was proposed. However, the proposed new system acquires appropriate control gains to drive the auxiliary mass to the desired value. Therefore, the new design method of the PD controller is proposed and verified in numerical simulation.
