基于ITAE的天线伺服系统的自寻优模糊控制

内容简介：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，可设计基于ITAE 的模糊自寻优控制器，实现对参数进行自寻优以使系统性能达到 ITAE 最优。对于天线伺服系统，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。

Abstract：In order to achieve optimal control of the dynamic performance and stability of antenna servo system, this paper designed a self-optimal fuzzy controller based on ITAE, by which the parameters can be self-optimal to achieve the best system performance. For the antenna servo system this article selected, the author adopted the general procedure of the fuzzy controller design, and then revised the adjustment factors with ITAE index as objective function, thereby enabling the system to achieve superior performance. The author carried on the simulation in the MATLAB environment and compared with the conventional PID controller's performance. The result showed that the response of self-optimal fuzzy controller based on ITAE was superior to the traditional PID controller in the response speed, stable precision and robust.
