Abstract: |
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. |
