Abstract
This paper shows a design method for a PI-D controller's gains which is utilized for driving active mass dampers using a neural oscillator. In the system, the output of the neural oscillator synchronized with structure responses is not only used as a rhythmic command, but also used to decide the desired value of the auxiliary mass. In addition, in order to drive the auxiliary mass to the desired value, the position control system consisting of a PI-D controller is used. In our previous study, the design method for PD gains as the position controller has been discussed. However, it is not practicable that using only P and D gain, because the rapid acceleration was happened when the driving direction of the auxiliary mass changed. Thus, in this paper, to moderate the acceleration response of the structure, the PI-D controller having I gain is used instead of the PD controller. Additionally, the design method of the PID controller is also discussed from a vibration control point of view. As a result of the numerical simulation shaken by earthquake, it was clear that the system using PI-D controller provided better effects for structural vibration mitigation than the system using P-D controller.
