摘　　要：针对传统马铃薯辊式联合收获机清洁除杂装置中的压力继电器不能及时控制电磁阀阀芯移动而造成液压马达等执行装置损坏的问题,以4UL-2型收获机为研究对象,设计了全新的伺服阀控液压马达调速换向系统,给出了相关元器件的传递函数;并利用MatLab软件进行了阀控液压马达系统的建模与仿真,根据系统稳定性要求及波德图中的幅值裕量和相位裕量计算了相关控制参数,最后通过Simulink仿真验证和优化控制参数。The results of pressure relay can not be control solenoid valve spool movement timely in impurity cleaning de- vice of the traditional roller type potato harvester which damaged to hydraulic motor and execution device. As a result, with 4UL-2 type harvestingmachine as the research object, design of a newly control reversing system about servo valve controlled hydraulic motor, then gives the transfer function of the relevant components. Modeling and simulation of servo valve controlled hydraulic motor system by using Matlab software. Calculated the relevant control parameters according to the system stability and Bode diagram of the amplitude margin and phase margin, at Last the control parameters were simulated and optimized with Simulink.
