中文摘要:

针对三相四线制有源滤波器直流侧电压PI控制存在超调比较大、动态响应速度慢等缺点,设计了一种采用模糊控制与PI控制相结合的模糊PI复合控制器。该控制器将输入变量进行模糊化,通过模糊推理控制模糊输出变量,以此实现在线修改参数的目的。分析了直流侧电压PI控制的基本原理,利用模糊控制器的双输出对PI控制器的参数进行整定,给出了二维模糊PI控制器的设计过程。MATLAB仿真结果表明,该方法超调小、动态响应速度快,能满足负载突变工况的要求,验证了所设计的模糊PI控制器的有效性和优越性。

英文摘要:

Due to the disadvantages which the PI control have such as relatively large overshoot, slow dynamic response and other shortcomings in the three-phase four-wire active filter DC-side voltage, design a mixed fuzzy PI controller combined fuzzy control with PI control. The controller fuzzes input variables and produces output variables which are fuzzy controlled by fuzzy inference, in order to achieve the purpose of modifying the parameters online. Analyze the basic principle of DC voltage PI control, use the dual-output of fuzzy controller to adjust the parameter of PI controllers and give a two-dimensional fuzzy PI controller design process. MATLAB simulation results show that this method produces small overshoot, fast dynamic response. Therefore, this method meets the requirements of mutation load conditions and finally verifies the validity and superiority of the fuzzy PI controller.
