Abstract

In this thesis, the currently feedback control algorithms used in the polarization controller, including simulated annealing algorithm and gradient algorithm were analyzed. On this basis, a new method of polarization control feedback algorithm based on fast locating algorithm was proposed to solve the defects of the original algorithm, such as poor convergence and long time consuming search. It can reduce convergence time and improve the response speed of the polarization controllers. This new endless polarization control algorithm using 4-plate polarization controller was proposed and demonstrated. The results showed that the response time of the polarization controller was less than 1ms. The control of polarization was achieved and the output polarization state was stable while the light intensity fluctuated less than 2%, which could run endless reset freely.
