Lyapunov redesign of analog phase-lock loops

The second method of Lyapunov is proposed as a method for analyzing the stability and tracking of the nonlinear phase-lock loop model. It is shown that a fairly regular procedure, known as Lyapunov design, which is quite well known in the area nonlinear control theory, is applicable to solving this class of problems. The ability of loops designed using these techniques to track a phase step is also proven.<
