Comparison of several types of differentiation algorithms has been performed in the paper Wang, Zheng, Efimov, and Perruquetti [(2018). Differentiator application in altitude control for an indoor blimp robot. International Journal of Control, 1-10. Retrieved from

] with application to a robotic blimp altitude control. Unfortunately, one of the differentiation methods, the algebraic differentiator, has not been applied properly. The clarifications and the new comparison results are given in this note.
