| 摘 要： | 研究了基于特征模型的自适应控制方法在高超声速飞行器姿态控制中的应用。对一类非线性强耦合以及大范围参数不确定性的类X-20高超声速飞行器无动力滑翔段六自由度动力学模型,建立含耦合的多输入多输出(MIMO)特征模型,并设计基于特征模型的黄金分割控制器。控制律设计中通过对非对角元控制量强制一步滞后,使得各通道控制量可以计算简单。最后通过飞行高度和速度大范围变化的长时间飞行过程中姿态角的跟踪控制仿真,验证了控制器的鲁棒性和适应性。

| Abstract: | A characteristic model-based adaptive control method is considered for the attitude control for a hypersonic vehicle.An MIMO characteristic model is established for a 6-DOF X-20 analogous hypersonic vehicle dynamic model during it's unpowered cruising phase.This model is nonlinear,strong couple and with parameters of great uncertainty.The Gold Section adaptive controller based on the characteristic model is designed,and the control algorithm is simplified by forcing one step time-delay of the non-diagonal c... |
