Exploration and Research on Extension Control

In this paper the structure and implementation of extension controller are developed basing on its design method by the authors in references[1] and[2]. Concept of the upper extension controller and basic extension controller are discussed. Impementation of the upper extension controller and improvement of the control algorithm in the basic controller are devioped. Results of simulation on linear, large time delay and non-linear systems show the extension control is of good performance and prospect.
