锁相环一般采用线性分析,相平面图,近似计算法以及计算机模拟来设计。设计中对锁相环非线性模型的稳定性缺乏分析手段。控制理论中称为李雅普诺夫的新方法近来已用于三阶环的设计中,证明其非线性模型是稳定的。本文所述的方法对于大多数模拟锁相环是稳定性分析和设计的一种有效方法。业已证明用此法设计的锁相环确能跟踪相位跃变。
Phase-locked loop is generally linear analysis, phase plan, approximate calculation and computer simulation to design. The stability of the non-linear model of the PLL in the design lacks analysis tools. A new method called Lyapunov in control theory has recently been used in the design of third-order loops, proving that the nonlinear model is stable. The method described in this article is an effective method of stability analysis and design for most analog phase-locked loops. It has been demonstrated that phase-locked loops designed in this way are capable of tracking phase jumps.
