摘要
某遥测设备因转动惯量大、机械谐振频率低和伺服系统带宽低,导致在跟踪加速度较大目标时,伺服系统产生较大动态滞后的问题,在原有环路分析的基础上,通过在位置环增加欠补偿的一阶微分前馈信号,对伺服实现复合控制,有效改善天线动态滞后,提高了跟踪的稳定性。
Large-diameter antenna has large moment of inertia,low mechanical resonance frequency,and low bandwidth of the servo system.It causes that the device will produce a large dynamic lag when tracking fast-changing targets.Based on the original loop analysis,the composite control technology is realized by adding a first-order differential feedforward signal with under compensation in the position loop,which improves the dynamic hysteresis of the antenna effectively and improves the tracking stability.
