This paper describes the control system design method concerning the feedforward control to cancel disturbance forces, including feedback control and their experimental considerations. There are two kinds of active vibration control devices. One is the type using a fixed point such as an active vibration absorber (AVA). The other is the type using an auxiliary mass such as an active dynamic vibration absorber (ADVA). The design methods for both the AVA and ADVA are shown here, and the control efficiency of ADVA is compared with that of AVA. Also, we have built two test rigs to simulate a large structure with AVA or ADVA. In order to carry out fast computation, including the estimation for disturbances, we have used the digital signal processor (DSP). The experimental results of AVA and ADVA are in good agreement with their simulation results. In conclusion, the disturbance forces are perfectly cancelled, and output zeroing is actually realized when the disturbance frequency is exactly equivalent to the design frequency of the observer. We have confirmed that the proposed disturbance cancellation control is very useful for active vibration control.
