PID算法优化在光纤稳相传输系统中的应用研究
Research on the application of PID algorithm optimization in optical fiber phase-stabilized transmission system
摘要
Abstract
To enhance the stability of the phase-stabilized fiber optic transmission system,an investigation is conducted based on its fundamental structure and transfer function to analyze the relationship between phase drift,overall stability,and the pa-rameters of the proportional-integral-derivative(PID)algorithm.Simulations under various parameter configurations revealed that increasing the proportional coefficient significantly suppresses phase drift,improving system stability by 2～3 orders of magnitude,optimizing the integral parameter helps mitigate noise,enhancing long-term stability by approximately one order of magnitude,and adjusting the derivative parameter reduces system oscillations,thereby boosting short-term stability by one or-der of magnitude.The results demonstrate that P、I、D parameters optimization can effectively enhance system stability without any modifications to the hardware architecture.关键词
