Research on Compound Control Method of Aircraft Maneuvering Trajectory

以某型典型飞机为研究对象,以筋斗机动为例进行控制验证。通过设计控制器并利用遗传算法进行合理的参数配置来达到满足性能指标的要求,在不改变原PID控制结构的基础上,设计前馈加反馈的复合控制器对参考模型进行跟踪,用复合控制方法以解决目前机动参考轨迹跟踪快速性和准确性较差的问题。结果表明各指令信号的跟踪效果较好,证明了所设计的复合控制器可以有效地补偿外部干扰对系统的影响,同时还能提高系统的控制精度,解决了飞机机动决策轨迹生成后需要合理和快速的轨迹跟踪的问题。

In this paper,a typical aircraft is taken as the research object,and the loop maneuver is taken as an example to verify the control.By designing the controller and using genetic algorithm for reasonable parameter configuration to meet the requirements of performance indicators,on the basis of not changing the original PID control structure,a compound controller with feedforward and feedback is designed to track the reference model,and the compound control method is used to solve the problem of poor speed and accuracy of the current maneuvering reference trajectory tracking.The results show that the tracking effect of each command signal is good,which proves that the designed composite controller can effectively compensate the influence of external interference on the system,at the same time,improve the control accuracy of the system,and solve the problem of reasonable and fast trajectory tracking after the generation of aircraft maneuver decision trajectory.
