摘　　要：为实现天线伺服系统的动态性能与稳定性能达到最优控制的目的。提出并设计了基于ITAE的模糊自寻优控制器,可实现对参数进行自寻优以使系统性能达到ITAE最优。对于选取的天线伺服系统,采用模糊控制器设计的一般步骤设计模糊控制器,再以ITAE积分性能指标作为目标函数,对调整因子不断进行校正,以使系统性能达到最优。在MATLAB环境下对系统进行了仿真研究,并与常规PID控制进行比较。结果表明基于ITAE的模糊自寻优控制器的响应特性远优于传统的PID控制器,响应速度更快,稳态精度更高,鲁棒性更强。In order to make the dynamic performance and stability of antenna servo system to achieve optimal eontrol purpose. This paper designed a self-optirnal fuzzy controller based on ITAE. The parameters of this method can be optimized to make the system performance optimal. For the antenna servo system this article selected, we can design fuzzy controller with the general procedure of the fuzzy controller design. And then revising the adjustment factors with ITAE index as objective function, thereby enabling the system performam：e to achieve superiorly. We carried on the simulation in the MATLAB environment and compared with the conventional PID controller＇ s performance. The result shows that the response of self-optimal fuzzy controller based on 1- TAE is superior to the traditional PID controller, and the response speed is faster,
