摘要
受到复杂飞行环境以及自身装配精度的影响,空地导弹在飞行过程中气动参数快速变化并且存在模型不确定性.为了解决这一问题,提出了一种基于非递归方法的空地导弹姿态控制方法.该方法通过干扰观测器观测模型不确定性和气动参数的摄动,并通过非递归设计方法进行前馈补偿,实现系统的稳定.最后,针对某型空地导弹的俯仰通道模型进行数字仿真验证.仿真结果表明,所设计的控制器具有强鲁棒、快速收敛等控制性能.与经典控制方法和其他递归类方法相比,该方法收敛速度提升约50％,同时该控制器结构简单,便于在实际工程中应用.
Abstract
Affected by the complex flight environment and assembly accuracy, the aerodynamic parameters of air-to-ground missile change rapidly during flight, and the model is uncertain. In order to solve this problem, an attitude control method of air-to-ground missile based on non-recursive method is proposed in this paper. A disturbance observer is used to estimate the model uncertainty and the perturbation of aerodynamic parameters, and the feedforward compensation is imple-mented by non-recursive design method to achieve stability of the system. Finally, the pitch channel model of a certain type of air-to-ground missile is verified by digital simulation. The simulation results show that the designed controller has strong robustness and fast convergence control performance. Compared with the classical control method and other recursive meth-ods, the convergence speed of this method is increased by about 50％. At the same time, the controller has simple struc-ture, which is advantageous for the practical engineering to apply.
