某雷达控制系统性能分析

Performance analysis of a radar control system based on Simulink

介绍了Matlab语言的建模仿真工具Simulink软件包的功能。基于Simulink,对按经典控制理论频域法设计和现代控制理论极点配置法设计的某大型雷达控制系统动态性能进行了仿真和分析,探讨了频域法和极点配置法对于某大型雷达控制系统的不同情况下性能指标的影响,最后得出按现代控制理论设计的大型雷达控制系统比按经典控制理论设计的控制系统具有更好的性能指标。对利用Simulink分析复杂控制系统的性能具有指导作用。

The modeling and simulating functions of Simulink software package in Matlab were introduced briefly. Based on Simulink, we carried out simulation and analysis on dynamic performance of a certain type of large radar control system, which was designed respectively by frequency-domain method of classical control theory and pole-assignment method of modern control theory. Then, we studied the influence of frequency-domain and pole-assignment methods on performance of the radar control system under different conditions. Our conclusion was that the radar control system designed according to modern control theory has better performance than the one designed according to classical control theory. The paper can be taken as a reference for using Simulink in analyzing the performance of complex control systems.
