Abstract :
A nonlinear approach to control chaos behavior in phase locked loop (PLL) is proposed. By applying the control algorithm, it is shown that the chaotic state of the PLL dynamics can be augmented freely regardless of its initial trajectory. In this paper, both the stability analysis and the necessary mathematical proofs of the controller are given. These are further demonstrated by simulation results
