摘　　要：在拖拉机作业过程中,根据不同的工况,需要不同的发动机转速,以满足动力性与经济性要求。提出了一种可以设定发动机高低转速的控制策略,选择高转速可以获得动力性,选择低转速可以保持经济性。利用MATLAB中的Simulink模块对控制策略进行建模,通过仿真分析与实车测试,验证了控制策略的正确性。During the tractor operation, it is necessary to set different engine speeds to meet the requirements of power performance and fuel economy when the tractor works in different conditions. One control strategy is proposed which can set high and low engine speeds. The high speed is chose to get power and the low speed to keep fuel economy. The control strategy is modeled and simulated by MATLAB Simulink module, and then tested on the tractor. Finally, it is verified to be correct.
