为提高光电跟踪伺服系统的跟踪精度,满足现代航空、航天的需要,在基于速度滞后补偿、加速度滞后补偿原理的基础上,提出了一种适合于跟踪快速运动目标的位置超前抑制方法。并分析了位置超前抑制参数对伺服系统跟踪精度的影响,确定了参数选取原则。在光电跟踪伺服系统的仿真实验中,将其与前馈内模控制技术相结合,大幅度的减小了跟踪误差,有效的提高了系统的跟踪精度。

In order to improve the tracking accuracy of electro-optical servo system for meeting the need of modern aviation and aerospace, based on the principle of speed delay compensation and acceleration lag compensation, a position ahead inhibition method for fast moving target was proposed. Then the effect of position a head inhibition parameters on servo system's tracking accuracy were analyzed, and the principle of parameter selection was determined. In the electro-optical tracing servo system simulation experiment, combined with the feedforward internal model control technology, the tracing error was greatly reduced, and the tracking accuracy was effectively improved.
