Description: 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 Platform: |

Description: 适当选择辅助变量，使之满足相应条件，参数估计值就可以是无偏一致。估计辅助变量法的计算量与最小二乘法相当，但辨识效果却比最小二乘法好的多。尤其当噪声是有色的，而噪声的模型结构又不好确定时，增广最小二乘法和广义最小二乘法一般都不好直接应用，因为他们需要选用特定的模型结构，而辅助变量法不需要确定噪声的模型结构，因此辅助变量法就显得更为灵活，但辅助变量法不能同时获得噪声模型的参数估计。-Choose appropriate secondary variables, meet the relevant conditions and parameter estimate can be unbiased consistent. Estimated auxiliary variable method calculation and least square method is quite, but the identification effect is much better than the least square method. Especially when the noise is colored, and noise model structure and not sure, augmented the least squares and the generalized least squares method is generally not used directly, because they need to choose specific model structure, and auxiliary variable method does not need to make sure that noise model structure, so the auxiliary variable method is more agile, but not at the same time auxiliary variable method for noise model parameter estimation.
