Connecting of integrated fiber systems depends on the polarization of the light at the output of polarization controllers based on solenoid, as squeezer fiber is suitable for coherent fiber optic systems because of its low insertion loss as well as low power penalty. However, the stability in open loop of the solenoid caused by their magnetic circuit affects the performance of these polarization controllers and limits their applications. To improve stability performance, first; a feedback PID corrector is proposed to correct the dynamic response. Then, the authors propose to study the effect of electrical parameters variations of the PID gains of solenoid. Finally, the artificial neural network is using to predict the PID gains that will correct the solenoid dynamic response. The simulation results show the need to adjust the PID corrector in the event of system parameter changes to maintain the optimum dynamic response.
