摘　　要：根据实验室现有的PMD(偏振模色散)补偿实验系统的需要,设计了一种基于DSP的实时控制系统。讨论了该实时控制系统的硬件和软件的设计与实现,对硬件电路进行了总体设计,分别对各部分的DSP最小系统、A/D采样硬件电路和D/A控制硬件电路进行了详细的分析和设计。介绍了软件的工作流程,设计了PSO算法模块在DSP系统中的实现。将该实时控制系统应用到PMD自适应补偿实验中进行了验证。结果表明,所设计的PMD自适应补偿实时控制系统对一阶和二阶PMD的补偿效果很好。According to the needs of PMD （Polarization mode dispersion） compensation experimental system in laboratory, a DSP-hased real-time control system is designed. The hardware and software design and implementation of the real-time control system are discussed. A hardware circuit is designed, including all parts of minimum DSP system, A/D sampling hardware circuit and D/A control hardware circuit. Software and workflow of the system are introduced. The realization of the PSO algo-rithm module in DSP system is designed. The real-time adaptive control system applied to the PMD adaptive compensation is verified. The result shows that the designed PMD compensation adaptive real-time control system has a good effect on the first order and the second order PMD compensation.
