本文介绍了应用数字仿真技术进行多参数寻优的方法对飞机纵向突风减弱的一种控制系统进行优化设计的原理和结果。在该控制系统中应用升降舵和襟副翼反应求自下述四种敏感元件的返馈信号:1.安装在驾驶员座位处的法向线加速度传感器;2.俯仰陀螺;3.信仰速率陀螺;4.俯仰角加速度传感器。后三者是安装在飞机的重心处。本文给出了单纯形法数字仿真多参数寻优的程序框图,对该方法的寻优原理作了简要说明。文中还给出了算例计算结果和结论性的意见。
This paper introduces the principle and result of optimizing design of a kind of control system which reduces the longitudinal gust of aircraft by applying the method of multi-parameter optimization by digital simulation technology. In the control system, the elevator and the flaperon are used to respond to the feedback signals from the following four sensitive components: 1. normal line acceleration sensor installed at the driver’s seat; 2. pitch gyro; 3. belief rate gyro ; 4 pitch angle acceleration sensor. The latter three are installed at the center of gravity of the aircraft. In this paper, the block diagram of multi-parameter optimization of simplex digital simulation is given, and the optimization principle of this method is briefly described. The paper also gives the calculation results and concluding comments.
