摘要
针对三相桥式全控整流电路、滤波电路及可控整流电源系统常见负载特性进行了分析和建模。采用智能控制方法设计满足可控要求的智能调节器,应用响应曲线斜率法在线辨识系统过渡过程的快慢,针对快响应过程和慢响应过程采用相应的模糊控制策略。最后用仿真实验验证该调节器的有效性。模糊控制规律应用于非线性、复杂时变的可控整流电源可取得良好的控制效果。由仿真结果可知,该模糊控制调节器能够适应负载结构和参数的变化,而对于电源的扰动该系统也有很好的抗扰能力。
In terms of three-phase full bridge controlled rectifier, filter circuit and the common loads characteristic , mathematical models were built and analyzed. An intelligent control method was adopted to design the intelligent regulator, the respond curve slope method was applied to identify fast and slow of transition process, according to the rate of the transition process, the fuzzy control strategy can be classified into fast response and slow response. The simulation results show its practicability. Fuzzy control rule was applied to nonlinearity and complex time-change of the controlled rectification power supply. The fuzzy control strategy can adapt the change of load structure and parameter, and has antijamming ability as well.
