飞机引导控制指令的选择直接影响到飞行控制性能,对引导控制指令的种类和优劣进行研究具有重要意义。首先,以纵向为例,分析认为可选择的引导控制指令有俯仰角指令、法向过载指令和垂直速率指令;然后,在几个合理假设的基础上,采用理论分析方法对上述三种引导控制指令进行比较,所得结论如下:在抑制风对迎角、高度的干扰,以及抑制参数摄动对高度的干扰等方面,能力由高到低分别为过载指令、垂直速率指令和俯仰角指令。最后,通过仿真对上述结论进行了辅助验证。
The choice of aircraft guidance control command has a direct impact on the flight control performance, which is of great significance for the study of the types and advantages and disadvantages of guidance control commands. First of all, taking longitudinal as an example, it is considered that there are pitch control instructions, normal overload instructions and vertical speed instructions for the optional guidance control instructions. Then, based on a few reasonable assumptions, theoretical analysis is used to analyze the above three guidance controls The conclusions are as follows: The ability to suppress the wind on the angle of attack, the height of interference, and inhibit the parameter perturbation and height interference, the ability from high to low, respectively, for the overload command, vertical rate command and pitch angle command. Finally, the above conclusion is verified by simulation.
