以液压挖掘机为研究对象，对其自动作业过程中工作装置的轨迹规划、非对称液压缸的动特性，以及控制策略的选择等一些关键技术作了较深入的研究，从而为进一步开展商品化研究奠定了理论基础。
Taking the hydraulic excavator as the research object, some key technologies such as the trajectory planning of the working device in the automatic operation process, the dynamic characteristics of the asymmetric hydraulic cylinder and the selection of the control strategy are deeply studied, so as to further commercialize Research laid the theoretical foundation.
