The purpose of this paper is to present an adaptive algorithm approach to control the vibrations of an aircraft structure and also use low power based system by real time implementation of the adaptive algorithm using ARM7 LPC2148 Processor. The adaptive algorithm used is Least Mean Square (LMS) the method used is steepest descent. LMS algorithm is an effective algorithm to reduce the vibrations and it does not require complex computations hence complexity of the system is reduced. The KEIL micro vision4 software is used. The programming language used is embedded C. The power consumption comparison of the ARM7 processor with other DSP processors is done.
