Agricultural sprayers are utilized in applying pesticides to control pests and diseases in crops. The increase in machine size and a better control system have been associated with increased productivity, improved efficiency and minimized the impact of the chemical on the environment. However, wider booms may contribute to application error due to the difference in speed between the inner and outer boom section when applying in curvilinear passes. Field tests were conducted in three irregular shaped fields with varying terrain using a 36.6-m self-propelled sprayer with a turn compensation technology. The results showed that turning occurred near the grassed waterways, boundaries and end of headlands. The product was applied during turning to 19.0% of Field 1, 17.8% of Field 2 and 22.5% of Field 3. These could have been the percentage of field areas that may receive more or less product if the sprayer was not equipped with turn compensation technology. As expected, the speed difference between the inner and outer boom increases as the radius of turn decreases. The speed difference could translate to an under-application on the outer boom section where the speed is much faster and over-application on the inner boom section where the speed is slower. The application errors from such speed differential could vary from − 48.2 to + 1058.0%, depending on the turning radius. However, the pulse width modulation system implemented duty cycles based on turning speeds, which resulted to a 90.0% application rate uniformity across the field regardless of the travel path during operation.

农业喷雾器用于施用杀虫剂以控制农作物的病虫害。机器尺寸的增加和更好的控制系统与生产率的提高、效率的提高以及化学品对环境的影响最小化有关。但是，由于在曲线通道中应用时，内和外悬臂部分之间的速度差异，较宽的悬臂可能会导致应用错误。使用具有转弯补偿技术的 36.6 米自行式喷雾器，在三个不同地形的不规则形状场地进行了现场测试。结果表明，转弯发生在草地水道、边界和岬角末端附近。该产品在转向区域 1 的 19.0%、区域 2 的 17.8% 和区域 3 的 22.5% 时应用。如果喷雾机没有配备转弯补偿技术，这些可能是可能获得更多或更少产品的田间区域的百分比。正如预期的那样，内臂和外臂之间的速度差异随着转弯半径的减小而增加。速度差异可能转化为速度快得多的外臂部分应用不足，而速度较慢的内臂部分应用过度。这种速度差的应用误差可能从 - 48.2 到 + 1058.0% 不等，具体取决于转弯半径。然而，脉宽调制系统根据转动速度实施占空比，这导致整个场地的施用率均匀性为 90.0%，无论操作期间的行进路径如何。
