摘要
in order to give another solution to the tracking problems of parametric strict feedback form systems, new robust controllers are designed which has no need to identify the unknown system parameters. The global boundness of all the signals in the control system (that is x, y, u) can be guaranteed, in addition, if the upper bounds of the unknown parameters are known a priori, the output tracking error can be made arbitrarily small. The new robust controllers can be applied directly to the case that the parameters are time varying and bounded, while the existing adaptive controllers can not.
