摘要: 在分析总能量控制理论的基础上,提出一种简单实用的飞机飞行速度/航迹解耦控制器设计方法,它以飞机能量控制和能量分配为内核,通过选择合适的误差反馈,采用工程上常用的试凑法,即可获得理想的解耦控制效果。以某型飞机为对象,以飞行速度/高度的解耦控制为例,验证了该方法的有效性。

Abstract: Total energy control(TEC) is a simple and effective design method for controller of flight speed/flight path. This paper proposed a new method based on controlling the amount of aircraft total energy and its distribution. This method adopt several error-feedback loops with simple PI controller to achieve good decoupling effect. Finally, digital simulations of this new control method is conducted with an aircraft on four of its typical situations, and the result validates this method's availability.
