%X 为实现拖拉机电液悬挂系统的准确控制，以福田雷沃欧豹TG1254拖拉机为研究平台，设计了一套拖拉机电液悬挂半物理仿真系统.该系统硬件平台主要包括拖拉机液压回路、传感器、数据采集装置等；软件平台采用SIT模块，联合LabVIEW和MATLAB建立控制器模型.设计自适应控制算法，实现系统的牵引力调节、位置调节和力位综合调节并进行了实车试验.在牵引力调节试验、位置调节试验和力位综合调节试验中，系统过渡过程时间均低于或等于6 s，系统超调量小于或等于25%，系统控制过程平稳，耕深稳定，实现作业质量提升.<br>A tractor electro-hydraulic suspension semi-physical simulation system was designed with the tractor LOVOL TG1254 as the research platform. The hardware platform of the system mainly included a tractor hydraulic circuit, a sensor and a data acquisition device. The software platform used SIT module, combined with LabVIEW and MATLAB to establish a controller model. An adaptive control algorithm was designed to realize the force control, position control and force-position comprehensive control of the system. A field experiment showed that the transition time of the system was less than or equal to 6s, and its overshoot was less than or equal to 25%. The control process was stable, the ploughing depth was stable and the operation quality was promoted
