摘要
为了提高电视跟踪系统的跟踪精度,提出了在不改变原有控制系统参数的基础上,根据系统的跟踪误差,在平稳跟踪阶段动态地并入积分环节,并且在跟踪误差较小时不去掉积分环节,从而构成高型系统的控制方法。实验表明,当积分增益K=2时,系统的最大跟踪误差为170'';当积分增益K= 4时,系统的最大跟踪误差为93''。
In order to improve the tracking accuracy of TV tracking system, a control method that constitutes a high-degree-mode (>mode-II) system by adding integral in smooth tracking period dynamically based on tracking error of the system and not removing integral in less error tracking period without changing intrinsic parameters of system is introduced. The experiments show that the maximal tracking error of the system is 170 arcsec when integral gain K= 2, and the maximal tracking error is 93 arcsec when integral gain K= 4.
