    The present work investigates Multi - channel Active Vibration Control (AVC) of a composite research wing model and shell structure using modified Filtered ¥ Least Mean Square (F¥LMS) algorithm on Field Programmable Gate Arrays (FPGAs). AVC, using Digital Signal Processing (DSP) techniques are cost effective. But FPGAs, consuming small silicon area, have emerged as a dominant technology in embedded applications with potential features like high speed processing and low power consumption. Prominent features like high-speed parallel processing architecture along with hardware reconfigurability facilitates its usage to be wide spread in signal processing applications. An adaptive active vibration control system based on feed forward modified F¥LMS algorithm implemented on FPGA hardware is presented here. The results from the Multi channel real time AVC studies are brought out in the paper.
