The CADS is a CW machine and a few particle loss will cause serious damage to the machine. Therefore, the quality of the or-bit control is an essential component towards the effi-ciency in operation, flexibility in machine studies. This paper describes an orbit correction implementation using singular value decomposition(SVD) of the response ma-trix and the simulation of its application to the CIADS injector II. This effort was achieved by exploiting the capabilities of Python, which provided the hands-on modules to develop the GUI code easily. Also involved in this effort was the code TraceWin, which was used to construct the virtual machine by providing the parame-ters of the Linac optics. Several iterations of the orbit correction may be required in order to obtain a satisfac-tory control of the orbit, because the the response matrix changes with iteration in an attenuating mode. After ap-propriate removal the redundancy steerers, a promising result of the orbit control was achieved.
