摘要
高精度姿态稳定是新一代卫星需要重点突破的关键技术之一。提出了一种基于现场可编程门阵列(FPGA)的新型磁悬浮飞轮永磁无刷直流电动机数字控制系统,以FPGA为控制器,阐述了组成系统的几个模块,实现了各种时序逻辑功能和PID控制算法。试验结果表明,系统运算速度快、控制精度高、能耗低,在满足飞轮精度要求的同时,提高了电路系统的可靠性,完全满足飞轮的高精度姿态稳定控制要求。
The high precision attitude stability of the new generation satellite platform was one of the most important key technologies which needed to break through.A new digital control system of brushless DC motor for magnetically suspended flywheel based on field programmable gate array(FPGA)was proposed in the paper.The components of digital system were also discussed.The system,which had the traits of high speed,low loss,high control precision,realized various time sequence logic function and PID control law.Th...
