Because of the differences of magnetic saturation and eddy current effects between different magnets, magnetic field tracking errors between different magnets is larger than 2.5 % at the Rapid Cycling Synchrotron (RCS) of Chinese Spallation Neutron Source (CSNS), and the induced tune shift is larger than 0.1. So larger tune shift may lead the beam to pass through the resonance lines. To reduce the magnetic field tracking errors, a method of wave form compensation for magnets of the Rapid Cycling Synchrotron was investigated on the magnets of CSNS/RCS. The wave form compensation was applied to CSNS/RCS commissioning. By performing wave form compensation, the maximum magnetic field tracking error was reduced from 2.5 % to 0.08 %, and the maximum tune shift over the ramping process was reduced from 0.1 to 0.004.
