高精度舰载光电跟踪伺服调速系统的研制

伺服控制的优劣直接决定光电跟踪系统的性能,速度环作为伺服系统三环控制的中间环节,其控制精度的高低直接影响到整个伺服系统的性能。该文设计一种高精度的数字调速系统,采用FPGA芯片作为核心控制器,选用数字光纤陀螺仪作为速度反馈装置,采用分段积分与积分限幅的PI控制算法。实验数据表明,系统具有很好的准确性和快速性。

Servo control directly determines the performance of photoelectric tracking system.As the intermediate link of three-loop control of servo system,the control precision of speed loop directly affects the performance of the whole servo system.This paper designs a high precision digital speed control system,which uses FPGA chip as the core controller,digital fiber optic gyroscope as the speed feedback device,and adopts PI control algorithm of piecewise integration and integral limiting amplitude.The experimental data show that the system has good accuracy and quickness.
