	Submicron orbit stability for a low emittance synchrotron light source are essential. Besides locating and removing the existing perturbations, active orbit feedback is applied to improve the orbit stability below sub-micron range from DC to a few hundreds of Hertz. Efforts to investigate orbit stability and stabilization at TPS will be addressed in this report.
