Polynomial
对于具体实验时,通常不是先给出函数的解析式,再进行实验,而是通过实验的观察和测量给出离散的一些点,再来求出具体的函数解析式。又因为测量误差的存在,实际真实的解析式曲线并不一定通过测量给出的所有点。最小二乘法是求解这一问题的很好的方法,本实验运用这一方法实现对给定数据的拟合。(For specific experiments, usually not first given function analytic formula, and then experiment but given by the experimental observation and measurement of a number of discrete points, and come back to find the specific function analytic formula. And because the presence of measurement error, the actual real analytic curve does not necessarily pass through all points of measurement given. The least squares method is a good way of solving this problem, the experimental use of this method of fitting the given data.)

Reconfigurable-flight-control
精密控制结构需要满足先进飞机的使命和对其引航的要求。这就要求飞行器的性能必须满足在低空飞行,低速飞行和大迎角攻击性飞行,全天候,昼夜工作的条件,并且新的控制技术应该成熟。这项工作提出了飞行控制时,状态变量和控制输入是由预先确定的限制范围内的系统控制系统的设计理念。在设计过程使用动态规划的概念。其基本思想涉及非二次泛函最小化。由于一系列限制因素,建议使用光滑函数。同时提出了该综合方法的优点。我们利用对F-18战斗机的纵向控制配置来说明该设计方法。(Indirect adaptive control for reconfigurable flight control is advocated. Specifically,
online static system identification using a moving window/batch estimation is implemented.
The ensuing linear regression is augmented with an intercept. The intercept parameter is
included to address the effects of trim change associated with the occurrence of a control surface
failure. Parameter estimate information is used to adjust the inner loop’s control gains, and
a command derived from the intercept estimate is fed forward to automatically retrim the aircraft.
The tracking performance of this automatic retrimming method, which relies on system
identification, surpasses the conventional approach of exclusively relying on integral action
for retrimming. These adaptive and reconfigurable flight control concepts are illustrated in
the context of a fighter aircraft’s pitch plane dynamics. The novel adaptive and reconfigurable
flight control system successfully handles a 50 per cent horiz)
