摘　　要：针对自抗扰控制器(ADRC)参数不易整定的不足,在ADRC的参数整定中应用了一种综合考虑了控制器动态性能和被控对象输入受限两方面的改进遗传算法,该算法应用到直流输电系统的整流器控制器的设计中可提高HVDC的鲁棒性。仿真结果表明所设计的整流器定电流自抗扰控制器具有良好的控制性能,对系统的外扰和模型参数的摄动具有良好的适应性,所提出的整流器自抗扰控制器设计方法有效可行。The security and stability of the HVDC system is ensured by the positive influence of its controller. Active-disturbance-rejection controller （ADRC） is adaptive for tlme-varying and uncertain disturbance. As for the complexity and difficulty of ADRC in tuning parameter, an improved genetic algorithm is used to tune the parameters of the ADRC. Both the controller＇ s dynamic performance and control constraints are taken into account in the parameters tuning of the ADRC. And the ADRC is used in the rectifier control of the HVDC system to improve the robustness of the HVDC system. The simulation results reveal that the controllers have a good performance and adaptability to the external disturbance and the model changes.
