摘要
为进一步提高跟踪雷达伺服系统的跟踪精度,详细论述了二维跟踪雷达伺服系统的跟踪误差数学模型。在此基础上,提出在其伺服系统中引入一种变增益交叉耦合控制理论和模糊控制相结合的控制算法,进一步设计出变增益模糊交叉耦合控制器,并在MATLAB/Simulink环境下搭建基于该控制算法的二维跟踪雷达伺服系统的仿真模型。经仿真对比和实际工程验证表明,所提出的控制算法可有效提高方位轴和俯仰轴之间的协调性,进而显著提高跟踪精度。
In order to further improve the tracking accuracy of the tracking radar servo system,this paper discusses the mathematical model of the tracking error of the two-dimensional tracking radar servo system in detail,on this basis,a control algorithm which combines the variable gain cross coupling control theory and the fuzzy control is proposed in its servo system,furthermore,the variable gain fuzzy cross coupling controller is designed,and the simulation model of the two-dimensional tracking radar servo system based on the control algorithm is built in MATLAB/Simulink environment,through the simulation comparison and the actual engineering verification,it can be concluded that the control algorithm proposed in this paper can effectively improve the coordination between azimuth axis and pitch axis,thus significantly improve the tracking accuracy.
