土壤改良剂变量撒施控制系统设计

Design of Variable Rate Soil Conditioner Control System

为了提高土壤改良剂的利用效率,降低土壤改良成本,设计了针对土壤改良剂的变量作业系统。重点研究开发了外槽轮式土壤改良剂撒施机构的液压驱动与电控系统;构建了控制系统的数学模型,通过数字仿真对控制参数进行了整定;对液压转速控制系统性能进行了测试。结果表明,该系统的实际控制效果可以满足土壤改良剂变量撒施的精度要求。

In order to improve the efficiency of soil amendment and reduce soil amelioration cost, variable rate applica- tion system designed for soil amendment. Hydraulic driver and electric-control system is developed for the fluted-wheel feed of soil amendment. The mathematical model of the control system is built and base on the digital simulation result the control parameters of hydraulic speed control system are adjusted. The results show that the control effect of the sys- tem can satisfy the variable rate application requirements of soil amendment.
