摘要
提出一种用于伺服驱动器或变频器中的分周比(分频比)功能的实现方案。先将输入正交脉冲序列四倍频,然后对单一的脉冲序列分频,再利用状态机产生相应的正交脉冲序列。该方案可以实现对电机或光栅尺等输出的正交脉冲序列进行任意整数倍分周。利用Actel公司软件Libro IDE及其FPGA产品APA300对该方案进行了仿真和实验,并给出了仿真、实验结果。仿真结果证明了方案的可行性。
A scheme to implement frequency divider in servo drivers is presented. At first, quadruple the input quadrature pulses,then divid frequency,finally,generate quadruple pulses. It＇s possible to achieve any integral multiple frequency dividing using this method. Simulation and experiment have been done and the results are given. The feasible of the scheme is proved by the simulation results and experimental results.
