This paper describes an experimental study concerning with the comparison of three multiple-channel active vibration control techniques for gear-set shaft with digital signal processor implementation. Although conventional passive vibration control techniques have achieved part of vibration cancellation, the parameter of passive system is usually fixed and the performance is limited in some special frequency range. In a practical application, the gear-set shaft of transmission system is operating in variable conditions. An adaptive hybrid active vibration controller for reducing transmission gear-set shaft vibration is proposed. The hybrid control algorithm is a combination of feedforward structure using filter-x least mean square algorithm and feedback structure with linear quadratic Gaussian theory. A frequency domain technique is used for achieving the control plant identification and controller design. The experimental works are carried out to evaluate the vibration attenuation performance of proposed techniques in transmission gear-set shaft.
