【摘要】：锁相环的跟踪性能是"锁相技术"课程教学中的重点内容。本文首先对锁相环的跟踪性能进行理论分析,然后基于VisSim仿真软件建立了二阶锁相环的仿真模型,并对锁相环的跟踪性能进行了仿真。给出了锁相环的输入信号存在相位阶跃和频率阶跃两种情况下的相位误差变化曲线和动态跟踪输出波形。通过仿真,学生更容易理解锁相环的动态跟踪性能,有助于为今后工作中进行锁相环电路的设计与应用打下良好的基础。
[Abstract]:The tracking performance of phase-locked loop is the key content in the course of phase-locked technology. In this paper, the tracking performance of PLL is analyzed theoretically, then the simulation model of second-order PLL is established based on VisSim simulation software, and the tracking performance of PLL is simulated. The phase error curve and the dynamic tracking output waveform of the input signal of PLL are given under the conditions of phase step and frequency step. Through simulation, it is easier for students to understand the dynamic tracking performance of PLL, which is helpful to lay a good foundation for the design and application of PLL circuit in future work.
