摘要:

针对滚仰式半捷联寻的制导导弹, 提出一种基于有限时间干扰观测器(finite time disturbance observer, FTDO)的探导控一体化滑模控制器设计方法。首先基于滚仰式半捷联导引头动力学模型和导弹制导控制模型, 建立了全状态耦合探测、制导、控制一体化控制模型。在模型中将不确定项和误差视为干扰, 通过有限时间收敛干扰观测器对干扰进行估计。对探导控一体化模型进行分块反演滑模控制律设计, 并验证了控制器的稳定性。仿真结果表明, 一体化控制方法提高了导弹对目标机动的响应能力和目标跟踪的稳定性, 并实现了比传统级联控制方法更小的脱靶量。

Abstract:

Aiming at the roll-pitch semi strapdown homing missile, a sliding mode controller for integrated design of detection guidance and control based on finite time disturbance observer (FTDO) is proposed. Firstly, based on the dynamic model of roll-pitch semi strapdown seeker and guidance and control model of the missile, the whole state coupling integrated control model of detection guidance and control is established. In the model, the uncertainty and error are regarded as disturbance, and the disturbance is estimated by finite time disturbance observer. The block backstepping sliding mode control law is designed for the integrated model of detection guidance and control, and the stability of controller is verified. Simulation results show that the integrated control method improves the response ability of missile to target maneuver and the stability of target tracking, which achieves a smaller miss distance than the traditional cascade control method.

Key words: disturbance observer, sliding mode control, integrated detection guidance and control, roll-pitch, semi stapdown
