The establishments of the mathematical model and the optimization objective function of the hydraulic system were in-troduced. Combining the complex mathematical optimization theory with MATLAB,M document was formed using the designed func-tion,then it was used in hydraulic system parameter optimization calculation,mistakes in the optimization process could be avoided,so optimal results could be gotten accurately and conveniently. It provides basis for the subsequent debugging and fault diagnosis of hy-draulic system.%介绍了液压系统的数学模型及优化目标函数的建立。将复杂的数学优化理论与MATLAB结合，建立自编函数形成M文件，运用于液压系统的参数优化计算，避免了寻优过程中的失误，从而可以准确、方便地得到寻优结果，为后续液压系统优化调试以及故障诊断提供依据。
