Summary:Accurate sensing of acceleration could provide improved performance for elevator control. Acceleration control is, however, seldom implemented, due to the unsatisfactory results of most acceleration measurement methods. We propose a polynomial predictive differentiator which delaylessly differentiates the available velocity signal. Polynomial prediction is justified, because the acceleration curve can be modeled accurately by a piecewise polynomial
