Abstract :
A new COD correction method suitable for orbit feedback has been already proposed. This is the eigenvector method with constraints, which can have both functions of global and local COD corrections. In this paper, we will present the effects of errors in beam position monitor (BPM) reading and steering magnet setting on the orbit correction. We will give analytical expressions of these errors. In addition, we will show results of computer simulations for the VSX light source, a VUV and soft X-ray high-brilliance synchrotron radiation source being planned at the University of Tokyo, and compare them with the analytical results
