Abstract : We are presenting new and efficient methods for numerical differentiation, i.e., for estimating derivatives of a noisy time signal. They are illustrated, via convincing numerical simulations, by the analysis of an academic signal and by the feedback control of a nonlinear system.
Keywords : Numerical differentiation iterated integrals orthogonal polynomials least squares operational calculus
