| Abstract: | A synchronous digital phase- locked loop (PLL) circuit has been used in the control system of a high speed camera. The main parts of the circuit consist of the digital phase detector and the digital error integrator. In this paper, not only the basic principle and mathematics equation of the digital error integrator, but also the typical PLL and it's prin-ciple are introduced. The synchronous PLL circut is used in the direct current servomotor system. It's performance is very good even in the conditions of the load variation and the components parameter drift. The error of the synchronous PLL is less than 3%. The experimental results show that the cricuit is good in performance and use. |
