Design of Phase-Locked Loop Circuit Based on Ant Colony Optimization Algorithm

In order to optimize the parameters of phase-locked loop circuit, an analysis of the stability and principle of phase-locked loop circuit is put forward by intelligent control theory, and its mathematical model and transfer function are established. And then, a parameter optimization method based on ant colony algorithm is proposed. The experimental results show that the phase-locked loop circuit designed in this method can supply a stable and accurate trigger signal. So this method can be applied into the phase-locked loop circuit for a great synchronous sampling required.
