The reduction of vibration in Aircraft/Aerospace structures as well as helicopter fuselage is becoming increasingly important. The active control techniques [1] using adaptive digital filters [2] are very much suitable amp; well proven. Hitherto this was being achieved using high speed Digital Signal Processors (DSPs). But the throughput requirements of these systems have strained the abilities of general purpose DSPs. The Field Programmable Gate Arrays (FPGAs) have emerged as an alternative to standard DSPs, since they13; incorporate arrays of dedicated multipliers, embedded memory amp; high speed I/O. The silicon resources of an13; FPGA lead to staggering performance gains x2013; while the fastest general purpose DSP can deliver up to 513; billion MAC/s (multiply-accumulate per second), leading FPGA devices can deliver more than 500 billion13; MAC/s x2013; thatx2019;s more than 100x faster. In the present paper attempt is made to realize the Active Controller using the Xilinx System Generator [3] on VIRTEX - 4 FPGA. System Generator is a DSP design tool from Xilinx that enables the use of The MathWorks model-based design environment, Simulink for FPGA design. Designs are captured in the DSP13; friendly Simulink modeling environment using a Xilinx specific blockset. All of the downstream FPGA13; implementation steps including Synthesis, Place and route are automatically performed to generate an FPGA13; programming file. Single channel Adaptive filter amp; system identification has been successfully implemented13; amp; Hardware Co x2013; Simulation has been carried out on Virtex-4 FPGA [4] using the XtremeDSP Development kit [5]. The methodology amp; results of this novel study are brought out in this paper.
