| Abstract: | This paper deals with a research on the nonlinear function of the three-order PLL, and its improvement by the numerical methods. The active nonlinear differential equations of the three-order PLL with the characteristic of the sine phase comparison were established and the program of numerical solution to the equations was worked out. Phase trajectories and time-response diagrams in various conditions were got. Influence on its nonlinear function put by electric circuit parameters and initial condition were analyzed and the ways to improve nonlinear function on it was found out. |
