| Abstract: | In this paper, we propose a new type of inverse called the filtered inverse. This inverse reconstructs the approximate value of the input to the original system without differentiators. The definition and the existence condition of the filtered inverse are given first. Then the stability and minimal realization of the inverse are discussed. Also, the stability of conventional inverses without differentiators are examined to show the necessity for filtered inverses. Furthermore, the application of such an inverse to servo system synthesis is discussed. |
