摘　　要：为了提升农用拖拉机发动机燃油效率,设计了一种负载敏感的发动机转速控制系统,并通过使用拖拉机仿真模型进行发动机转速控制器设计及优化。与田间试验测得数据对比可知:拖拉机模型模拟发动机转速和扭矩值的平均误差范围为≤5.0%,控制系统对拖拉机速度控制误差范围≤1.17%,发动机燃油效率指标单位体积燃油消耗(SVFC)、单位耕作面积燃油消耗(FCA)和每工作小时燃油消耗(FC)分别为23.0%~57.9%、4.1%~42.1%和7.2%~38.5%,与传统拖拉机发动机相比得到显著改善与提高。研究结果可为优化拖拉机发动机控制算法及提高拖拉机的燃油效率提供理论参考与技术支撑。In order to improve the fuel efficiency of agricultural tractor engine,this study designs a load-sensitive engine speed control system,and the engine speed controller is designed and optimized by using a tractor simulation model.The average error range of tractor model simulated engine speed and torque value is≤5.0%,the error range of control sys-tem on tractor speed control is≤1.17%,the engine fuel efficiency indexes of unit volume fuel consumption(SVFC),unit tillage area fuel consumption(FCA)and fuel consumption per working hour(FC)are 23.0%~57.9%,4.1%~42.1%and 7.2%~38.5%,respectively,which were significantly improved compared with the conventional tractor en-gine.The results of the study provide theoretical reference and technical support to optimize the tractor engine control al-gorithm and improve the fuel efficiency of the tractor.
