| 摘 要： | 针对当前高地隙植保机自动化程度不高、作业时行驶速度变化较大影响施药质量等问题,设计具备手动、自动切换功能的速度自动控制系统。以雷沃ARBOS高地隙植保机为研究平台,采用机电一体化控制方法对其变速执行机构、速度控制过程与特性进行分析,采用基于比例微分算法的速度控制方法,实时计算并控制速度执行机构的动作,实现行驶速度的自动调节。田间试验表明,高地隙植保机速度自动控制系统能够按照速度指令控制静液压行走驱动系统的输出,在平均行驶速度为0.21、0.83和0.94 m/s时,最大速度控制误差分别为0.05、0.10和0.10 m/s,满足高地隙植保机行驶速度控制的基本要求。

| Abstract: | With respect to problems including lack of automation and poor spraying quality due to varying speed existing in high-clearance sprayer,an automatic speed control system was developed for the high-clearance sprayer of LOVOL ARBOS by investigating its transmission mechanism and characteristics in speed control based on mechatronic control methods.A speed control method was used to control the speed executor based on proportion-differential algorithm to realize automatic adjustment of the vehicle speed.Field tests showed that the newly developed automatic speed control system could control the power output of the HST driving system to realize the desired speed.The maximum speed errors were 0.05,0.10 and 0.10 m/s when the desired value was set to 0.21,0.83 and 0.94 m/s,respectively indicating that the system could meet requirements for speed control of the high-clearance sprayer. |
