摘要
本文介绍了一种新的非线性分析方法──分解法,并通过引入数学机械化的方法,将其应用于非理想二阶锁相环路的分析,推导了捕捉过程中相位差、频率差的逼近解析解,分析了环路的稳定性,得到了环路稳态相差、稳态频差和捕捉时间等参数。
In the paper,a novel method of nonlinear analysis- Decomposition method is introduced. Depending on Mathematical Mechanization,it is used to analyze the second-order Phase-locked loops (PLL) with imperfect integrator, and the approximate analytic solution of phase error and frequency error are worked out. The stability is analyzed and the steady-state phase error, frequency error and pull-in time are obtained.
