摘　　要：针对稳瞄系统的性能有一定改进空间,而对象机械特性又改善受限的问题,试图从电气控制角度寻求更好的解决方法。为此,以某上反稳瞄系统为平台,对Luenberger观测器和LADRC(线性自抗扰控制器)两种能提高系统性能的先进控制算法进行了半实物仿真研究。首先,介绍了Luenberger观测器和LADRC的基本原理。其次,对某上反稳瞄系统的对象特性进行了分析,设计了基于两种控制模型的控制器参数。然后,运用MATLAB/Simulink工具和d SPACE半实物仿真系统,对某上反稳瞄系统进行了两种控制算法的对比研究。Luenberger观测器的控制性能相对较好,受噪声的影响,离工程实现还有一段距离。如何有效抑制噪声有待进一步研究。There is a certain room for improvement in performance for stabilized sighting system.However,to improve the mechanical properties of the object is limited.So it is conducted that trying tofind a better solution from the perspective of electrical control.Two advanced control algorithms ofLuenberger observer and linear active disturbance rejection control are expected to improve systemperformance.This paper presents the semi-physical simulation of both algorithms on some stabilizedsighting system.Firstly,introduced the basic principle of Luenberger observer and LADRC.Secondly,object properties of the sighting system are analyzed and two kinds of controller are designed.Then,acomparative study of two control algorithms on the sighting system was carried out by using MATLAB/Simulink tools and dSPACE hardware-in-the-loop simulation system.Control performance ofLuenberger observer is better,Affected by noise,it is still some distance away from the projectrealization.Thus,how to effectively suppress noise becomes the further study.
