| 摘 要： | 提出了一种速度给定系统模型，并给出实现该系统的电路图，用来解决控制系统在用模拟电路实现时，由于给定值扰动，使放大器饱和所导致的系统实际放大倍数降低，从而减慢系统响应速度的问题。通过仿真试验和在TDI摆扫航空相机中的应用试验表明，采用本文所述系统有效地提高了相机镜筒扫描速度系统的响应速度。

| Abstract: | To improve response speed of drawtube_scan_velocity control system is a key point for TDI pendular aeronautical camera to increase the imagery time and obtain relatively large viewing field.A mathematical model of given velocity system which was used to limit saturated zone of amplifier in analog circuit was given,as well as the circuit for implementation,because the saturated zone is one of the major reasons for declination of control system's practical amplification that results in decrease of response speed for the drawtube_scan_velocity control system.The proposed approach was tested in simulation and TDI pendular aeronautical camera.Experimental results show that the response speed of the drawtube_scan_velocity control system was effectively improved. |
