By considering the characteristics of non-linearity of hydraulic system，the AMESim software was used to establish physical model of the hydraulic system. Then the mathematical models of wet brakes were built and for the strategic models of incremental PID controller withi using of Matlab software，and which were co-simulated. The results show that the model built of the hydraulic system is effective，and the accuracy of the incremental PID servo control strategy to track the trajectory of the brake piston is quite high.
