| Abstract: | In the engineering practice of active vibration isolation, an effective multi-channel control algorithm is the prerequisite and basis for using multiple secondary force sources and error sensors to improve the vibration isolation effect. The distributed multi-channel adaptive (DMFxLMS) algorithm is adopted for the coupling of each channel and the increase of the calculation amount. The calculation process is deduced and the convergence conditions are given. Based on the NI PXI controller equipped with the Real-Time operating system, an active control experiment is constructed. On the platform, the experimental research of distributed multi-channel algorithm is carried out. The effect of active control is analyzed by changing the convergence step and filter order, and the effectiveness of the algorithm is verified. |
