The invention relates to an anti-swing control system of a crane, which comprises a sensing apparatus (14), a SIMOTION motion controller (16), a first SINAMICS driver (18) and a dolly mechanical drive apparatus (12). The sensing apparatus is capable of sensing position of a grab bucket of the crane, the SIMOTION motion controller is capable of calculating swing period of the grab bucket according to a sensing signal, and then calculating the deceleration time information and acceleration time information of a dolly according to the swing period, the first SINAMICS driver is capable of transferring the deceleration time information to a deceleration control signal, and then transferring the acceleration time information to the acceleration control signal. The dolly machinery drive unit is capable of controlling the dolly of the crane to perform slow movement according to the deceleration control signal or controlling the dolly of the crane to perform accelerated movement according to the acceleration control signal. The anti-swing control system of the crane is capable of increasing the control precision of the crane, and capable of increasing security and technical protection of a program.
