Abstract
In the practical application of finite time settling control (FTSC) and/or dead beat control, undesiable effect such as reset wind-up may be occured by input saturation of a controled object. We propose a new design method of FTSC system as model reference type, in which compensator acts softly to reduce the error between object and reference model, and prescribed effect wouldn't occur. And reachability conditions of the control system with saturation are investigated. Then the response characteristics of the system designed by the proposed method are compared theoretically with those desiged by using modern and classical control theories. And some numerical examples are presented. It is shown that the proposed method is a little inferior to the modern one in respect to the settling time while there is no input saturation. But best of all in respect to the stability for the object with input saturation.
