摘要
在分析了整周期采样必要性的基础上,提出了利用集成PLL电路实现整周期采样的方案,并针对磁力轴承系统的特点对电路参数进行了设计,同时对锁相环的锁相速度进行了改善.MATLAB仿真结果表明本方案可以有效地提取振动信号.
The necessity of integral period sampling is analyzed. On the basis, an solution scheme for integral period sampling is proposed, and improvement is added to the general PLL to get an faster phase lock speed for AMBs. The results of MATLAB simulation indicate that the vibration signal could be extracted effectively by using the proposed schema
