飞机飞行仿真中，对四个主要控制量，包括油门、升降舵、副翼及方向舵控制，分别提供持续2秒的随机大小的阶跃控制输入，四个控制量互相独立。可以用于飞行动力学系统辨识、参数识别等。-Flight simulation, the four main control volume, including throttle, elevator, aileron and rudder control, to provide for 2 seconds, respectively, a random step si

飞机系统辨识程序，对飞行器各个气动导数，通过最小二乘或递归最小二乘进行辨识。(Code for aircraft system identification, including the least squares or recursive least squares.)
