为了研制一种装有砷化镓霍尔传感器的自动挖掘机行程敏感油缸，建立了一套测量试验装置，并对设计参数进行了试验研究。测量系统本身是一种XZ工作台，具有X和Z方向的两个移动轴，分别安装在其上的传感部件，包括霍尔传感器。此外，为了获得高精度的测量系统的运动，一个新的滑模控制，它减少了抖动在控制回路中设置两个死区沿着切换线。滑模控制的未知参数估计的信号压缩方法。利用测量仪器对霍尔传感器的输出信号进行了分析。特别地，根据霍尔传感器在具有磁性标尺的活塞杆上的运动的检测信号进行了研究，并且获得了霍尔传感器与活塞杆之间的垂直距离，该垂直距离对检测信号产生直接影响。在此基础上，设计并制作了行程敏感缸。
In order to develop a stroke-sensing cylinder for automatic excavators equipped with Hall sensors of GaAs type, a measuring test facility is set up and used in investigating the design parameters. The measuring system itself is a kind of XZ table with two moving axes in X and Z directions, respectively, on which sensing parts, including Hall sensors, are installed. Furthermore, to attain a high precision of movement of the measuring system, a new sliding mode control is introduced, which diminishes chattering in the control loop by setting two dead zones along the switching line. The unknown parameters for sliding mode control are estimated by a signal compression method. The output signal from a Hall sensor was analyzed by using a measuring instrument. In particular, the detected signal according to the Hall sensor's movement on the piston rod, which has a magnetic scale, was investigated and the vertical distance between the Hall sensor and the piston rod, which gives direct effects on the detected signal, was obtained. Based on these results, the stroke-sensing cylinder was designed and fabricated.
