Comments on "Robust tracking control for rigid robotic manipulators"

摘要

In the original paper by M. Zhihong and M. Palaniswami (ibid., vol.39, p.154-9, 1994), a robust tracking control using a nominal feedback controller and a variable structure compensator for a rigid robotic manipulator with uncertain dynamics was presented. It is assumed that the model uncertainty is bounded. The author claims that this assumption is not necessarily correct and that the results obtained are therefore untenable.
