Comment on ‘Projection-based identification algorithm for grey-box continuous-time models’ by Ichiro Maruta and Toshiharu Sugie

Abstract

Although the paper by Maruta and Sugie (2013) makes an interesting contribution to the literature on the estimation of parameters in grey-box, continuous-time transfer function models, some of the simulation results are flawed and give a misleading impression of how the algorithm suggested by the authors compares with the well known and closely related SRIVC algorithm.
