| 摘 要： | 电动飞机电推进系统采用高效永磁同步电机作为主驱动,配备矢量控制器。飞机在巡航过程中不可避免地会遭遇突风,影响飞机的稳定飞行。通过建立电动飞机在巡航阶段遭遇突风时的空气动力学模型和电推进系统的动态响应数学模型,并对模型进行求解,给出了突风气象条件下电推进系统速度PI控制参数的设定方法。以某双座电动飞机的电推进系统为研究对象,采用MATLAB仿真和样机地面试验对速度PI控制进行了仿真分析和试验测试,对比了未考虑和考虑突风气象条件下的速度PI控制器的动态特性。仿真和样机试验结果表明:当飞机遭遇突风时,采用考虑突风气象条件的速度PI控制参数可以有效地降低螺旋桨的转速波动范围。

| Abstract: | An electric propulsion system of electric aircraft driven by highefficiency permanent magnet synchronous motor was equipped with a vector controller. Aircrafts are vulnerable to gust encounters, which can lead aircrafts to an unstable state. The aircraft aerodynamic model during cruise under gust and the dynamic model of the electric propulsion system of the electric aircraft were established and solved, and the setting method of PI control parameters of the electric propulsion system under gust was given. We simulated the twoseater electric aircraft using MATLAB, and then carried out the experimental tests on the ground. The simulation and experimental results showed that when the aircraft encountered gust, the speed PI control parameters considering the gust conditions could effectively reduce the speed fluctuation range of the propeller. |
