基于过载的制导炮弹非线性控制系统设计
|
摘要
对于制导炮弹而言,控制系统的重要性不言而喻,如果控制系统存在问题,轻则影响炮弹制导的精度,重则引发相应的安全事故。本文针对制导炮弹模型中的非线性及耦合性特征,提出了一种基于过载的制导炮弹非线性控制系统设计方法,通过构建炮弹过载时变模型的方式,在俯仰及偏航通道控制器的设计环节,增加了低通滤波器用以消除原本存在的"计算膨胀"问题,经非线性阻尼项,消除了外界扰动,然后运用Lyapunov理论,就系统本身的稳定性进行了验证,结果表明,吸引可以实现对指定过载的准确跟踪。
For guided projectiles, the importance of the control system is self-evident, if there are problems in the control system, the accuracy of guided projectiles will be affected slightly, and the corresponding safety accidents will be caused seriously. Aiming at the characteristics of nonlinearity and coupling in guided projectile model, a design method of non-linear control system for guided projectile based on overload is proposed, in the design of pitch and yaw channel controllers, a low-pass filter is added to eliminate the "computational dilation" problem. The external disturbance is eliminated by using the non-linear damping term, Then, the stability of the system itself is verified by using Lyapunov theory. The results show that the attraction can track the specified overload accurately.
