Closure to “Discussion of ‘Friction-Compensating Command Shaping for Vibration Reduction’ ” (2006, ASME J. Vib. Acoust., 128, p. 540)

Abstract

Dr. Shahruz is correct in asserting that exact cancellation of frictional terms is not possible. However, nowhere in our paper do we claim exact cancellation, nor does our method require exact cancellation of the friction effects. In fact, a large section of our paper is devoted to experimentally examining the effects of inaccuracies in the implementation of our technique. Therefore, we are alarmed that he has come to such a conclusion and that this journal would publish such an erroneous statement.
