This paper introduces a new synchrotron camera control system, which uses the speed control with good transient response and the phase discriminating and phase-demodulating technology with better characteristics to greatly shorten the frequency pulling process and make the system quickly enter the phase locking area, The invention achieves high synchronous photographing precision, wide synchronous photographing frequency range and short synchronous time so as to greatly improve the performance of the synchronous photographing control system. This article describes the design of the system, control system circuitry, system performance. The system has been successfully applied in the shooting range. System structure is simple, stable and reliable, have some practical value.
