针对平流层飞艇螺旋桨与直流无刷(DC)电动机匹配问题,建立了直流无刷电动机模型和螺旋桨模型;结合匹配设计和直流无刷电动机转速控制,在Simulink中设计了螺旋桨与直流无刷电动机控制系统仿真模型,研究飞艇在0~10m/s巡航速度下动力推进系统控制响应问题;采用图形用户界面(GUI)编写螺旋桨与直流无刷电动机匹配界面,开发了一种螺旋桨与直流无刷电动机匹配软件;得到了飞艇在0~10m/s巡航速度下,螺旋桨工作转速为535~1 071r/min,动力推进系统工作效率为0.558~0.593时推进系统匹配设计的工作曲线,为高空螺旋桨与电动机的匹配设计提供了参考依据.
In order to match the problem of matching between airship propeller and DC brushless DC motor, a direct current brushless motor model and a propeller model are established. Combined with matching design and DC brushless motor speed control, propeller and brushless DC motor control are designed in Simulink The system simulation model is used to study the control response of the propulsion system under the cruising speed of 0 ~ 10m / s. A graphical user interface (GUI) is used to write a matching interface between the propeller and the brushless DC motor. A propeller is developed to match the brushless DC motor Software was obtained. The working curves of propulsion system matching design of the airship at a cruising speed of 0 ~ 10m / s, working speed of propeller at 535 ~ 1 071r / min, and power propulsion system working efficiency at 0.558 ~ 0.593 were obtained for high altitude propeller and electric motor Matching design provides a reference.
