摘要：

The space optical remote sensor has high requirements for control precision and stable performance of actuator. In this paper, the effect of steady and variable speed control system is analyzed from structure, principle and simulation, according to the characteristics of phase-locked loop control technology. In order to improve the integration of system, the hardware circuit is achieved by FPGA, and correctness is proved on the basis of the running status of motor. Results show that phase-locked loop control system designed by FPGA can realize high precision steady speed control under 0.4 per thousand, in the condition of output frequency between 600Hz and 800Hz. When speed slope don't exceed 20Hz/s, the system can obtain smooth variable speed control, and track the input signal changes precisely. The design satisfies the requirements for the control system of optical remote sensor.
