One of the most serious problem we are facing is the number of estimated parameters is too big to be calculated by using a micro-computer. Moreover, genera feedforward adaptive control algorithm needs real-time system identification of the plant. In this study, we propose a simple method to attenuate only resonance peaks of vibration of cantilever beam based on MIT rule. The parameters to be estimated in real-time are only the amplitude and phase of a sinusoidal signal to cancel the vibration at resonant points of the beam. This simple algorithm never need previous system identification and reference signal as to be needed in general adaptive systems. Some experimental results show the efficiency of the algorithm.
