摘　　要：针对导弹飞行末段制导控制一体化设计中目标加速度信息难以直接测量的问题,提出了一种基于非线性观测器的自适应动态面控制方法。通过充分利用导弹中便于测量的信息,设计非线性观测器来估计目标加速度。在建立平面内制导控制一体模型的基础上,构建视线角速率动态面,采用自适应控制方法得到虚拟控制量,进而得到制导控制一体化控制律,并对其稳定性进行了验证。仿真导弹拦截三种目标运动形式的飞行弹道,进行了蒙特卡洛打靶试验,而后与未补偿目标加速度信息的自适应动态面控制方法进行对比分析,结果表明该控制方法能够有效削弱末段失稳现象。Aiming at the problem that the target acceleration information is difficult to directly measure in the integrated guidance and control at the end of the missile flight,an adaptive dynamic surface control method based on nonlinear observer is proposed.By making full use of the information in the missile that is easy to measure,a nonlinear observer is designed to estimate the target acceleration.On the basis of establishing the integrated model of in-plane guidance and control,the dynamic angle of line-of-sight angular velocity is constructed,and the virtual control quantity is obtained by adaptive control method.Then the integrated control law of guidance control is obtained,and its stability is verified.The simulated missile intercepts the flight trajectory of three target motion forms,carries out the Monte Carlo shooting test,and then compares it with the adaptive dynamic surface control method of uncompensated target acceleration information.The results show that the control method can effectively weaken the final instability phenomenon.
