| 摘 要： | 文章简要介绍了几种现代非线性优化算法,在两级偏振控制器和时延线级联补偿器结构的基础上,采用遗传算法作为偏振模色散(PMD)补偿中的反馈控制算法进行全局最优化,使偏振度(DOP)实现最大化,实现PMD补偿.文章对遗传算法在二阶PMD补偿中的应用进行了理论分析,并且设计了以TMS320C6711DSK为核心硬件的整套控制结构.

| Abstract: | In this paper,a number of modern nonlinear optimization algorithms are briefly introduced.On the basis of the structures of the two-stage Polarization Controller(PC) and the time delay line cascaded compensator,global optimization is realized to maximize the Degree of Polarization(DOP) by using the Genetic Algorithm(GA) as the feedback control algorithm in the Polarization Mode Dispersion(PMD) compensation.Theoretical analysis is made of the second-order PMD compensation and a complete set of control structure designed with TMS320C6711DSK as the core hardware. |
