	The algorithm in the feedback system has important influence on the performance of the beam orbit. PID algorithm is widely used in the orbit feedback system; however the deficiency of PID algorithm is big overshooting in strong perturbations. In order to overcome the deficiencies, Integral Separated PID algorithm is developed. When the closed orbit distortion is too large, it cancels integration action until the closed orbit distortions are lower than the threshold value. The implementation of Integral Separated PID algorithm with MATLAB is described in this paper. The simulation results show that this algorithm can improve the control precision.

The algorithm in the feedback system has important influence on the performance of the beam orbit. PID algorithm is widely used in the orbit feedback system; however the deficiency of PID algorithm is big overshooting in strong perturbations. In order to overcome the deficiencies, Integral Separated PID algorithm is developed. When the closed orbit distortion is too large, it cancels integration action until the closed orbit distortions are lower than the threshold value. The implementation of Integral Separated PID algorithm with MATLAB is described in this paper. The simulation results show that this algorithm can improve the control precision.
