高压直流输电智能控制器的设计

The Design of HVDC Intelligent Controller

针对传统PI控制器鲁棒性差、自适应差的不足,通过应用智能控制理论设计出高压直流控制器—Fuzzy-PI控制器,并用改进的遗传算法来对Fuzzy的隶属度函数等参数进行优化,使Fuzzy-PI控制器具有更好的适应性和更强的鲁棒性。根据优化方案设计葛洲坝—南桥直流输电工程控制器,并通过仿真验证了其理论精确性,工程实用性。

Because the robustness and the adaptive of traditional PI controller was bad enough,this paper describes application of intelligent control theory to design high voltage direct current controller-Fuzzy-PI controller.And it uses an improved genetic algorithm to optimize the Fuzzy membership functions of the parameters,so that Fuzzy-PI controller has better adaptability and robustness.According to the Best Design,Gezhouba Nanqiao controllers direct current transmission project is done,and simulation verified the theory＇s accuracy and practicability.
