A NEW TYPE CONTROL SYSTEM FOR SYNCHRONOUS PHOTOGRAPHY

本文介绍了一种新型同步摄影控制系统,它应用具有良好瞬态响应的速度控制和具有较为理想特性的鉴频鉴相技术,大大地缩短了频率牵引过程,使系统快速地进入相位锁定区域,实现了高的同步摄影精度、宽的同步摄影频率范围、短的同步时间,使同步摄影控制系统性能有较大的提高。 本文介绍了该系统的设计思想、控制系统电路、系统性能。该系统已成功地应用于靶场中。系统结构简单,工作稳定可靠,有一定的实用价值。

This paper introduced a new type of control system for synchronous photography. The speed control which has a good performance of transient response and the technique of frequency discrimination and phase detection which has a approach ideal characteristic were used. Therefore, the pull-in process of frequency was greatly shorted. This control system was rapidly draw into the phase locking range. The high precision of synchronous photography, wide frequency range of synchronous photography, and short synchronous time have been achieved. So, the performance of this control system was obviously improved. This paper described the design thinking, the skeleton diagram and the performance of this control system. This system has been successfully used in the range.
