This invention provides a multi-channel coordinated compensation method and system for an electro-hydraulic servo loading system, relating to the field of mechanical loading technology. For each coordinated compensation cycle, the mean error, phase error, and amplitude error of the main channel and each branch channel are calculated. Based on the mean error, phase error, and amplitude error of the main channel, the input commands for the main channel are corrected. Similarly, based on the mean error, phase error, and amplitude error of the main channel and each branch channel, the input commands for each branch channel are corrected. This invention solves problems such as amplitude attenuation and phase asynchrony in multi-channel loading control, effectively improving the control accuracy and stability of the mechanical loading instrument.
