摘 要:跟踪精度是机载光电成像跟踪系统的重要性能。为了提高系统的跟踪精度,采用复合控制对跟踪回路进行设计。首先,对跟踪系统中速度回路进行设计,然后分别对跟踪回路未加前馈和加前馈的控制方法进行设计。通过对两种设计方法仿真表明:复合控制将跟踪系统的跟踪精度由3′提高到0.03′。该方法已成功应用于某型机载光电侦察设备,提高了系统的跟踪精度,具有较好的使用效果。 关键词:机载光电成像跟踪系统;复合控制;速度回路;前馈控制;跟踪回路;跟踪精度
Abstract: Tracking precision is an important performance of airborne photoelectric imaging tracking system. In order to improving tracking precision, tracking loop was designed by compound control. First, designed velocity loop, then without feedforward and with feedforward control in tracking loop. Simulation show that the tracking precision was improved from 3′ to 0.03′ by compound control. This way has been applied to certain airborne photoelectric reconnaissance device, tracking precision was improved and applying result was good. Key words: airborne photoelectric imaging tracking system; compound control; velocity loop; feedforward control; tracking loop; tracking precision
