摘　　要：采用Luenberger观测器进行稳瞄系统的设计,关键在于观测器补偿器的设计及低通滤波器的频带选择。进行了离线仿真、基于dSPACE的半实物仿真、静态试验及动态扰动试验,通过各种滤波手段抑制了系统噪声,与各种常规控制方法进行了对比,系统稳定性、稳定精度及鲁棒性都得到了有效提高,试验取得了较好的效果。The steady sighting control system was designed using Luenberger observer technique.The key is the design of observer＇s compensator and how to choose the lowpass＇s frequency band.The MATLAB simulation,the dSPACE based hardware-in-the-loop simulation,the static experiment and dynamical disturbance experiment were achieved.The system noise was restrained through using all sorts of ways of filtering the waves.In contrast with general control ways,the system stability,stabilization precision and robust performance in this technique are improved effectively,a satisfactory result is achieved.
