A digital signal processor (DSP) implementation of an active vibration controller for reducing periodic vibration in a gear-set shaft is described in this paper. The proposed control algorithms are developed using μ-analysis to obtain robust stability and robust performance in experimental investigation. In experimental work, three different active vibration control algorithms are used, and their characteristics and performances are compared in various experiments. Apart from the traditional adaptive filter and the robust feedback control system, a hybrid controller combining an adaptive controller with a filtered-x least mean squares algorithm and a state feedback theory with a μ-analysis to obtain robust performance and fast convergence is proposed. The control plants are identified by the frequency-domain technique and implemented on a DSP platform. Experiments are carried out to evaluate the attenuation performance and characteristic of three control structures in gear-set shaft vibration. The experimental results indicated that all the three controllers are effective in reducing the gear-set shaft vibration and the hybrid controller demonstrated the best performance in experimental investigation.
