摘　　要：针对含有高阶时滞环节的储能变流器(PCS)控制系统,围绕参数设计难以兼顾时域和频域性能指标的问题,提出基于D分割法的多目标可视化设计方法。首选绘制系统稳定边界,其次分别绘制时域和频域性能指标随参数变化三维图,最后在统一坐标系中进行多目标寻优,进一步提高了系统的动静态性能。该方法具有直观清晰性,无需反复试凑,仿真和实验结果证明了该方法的有效性。For the power converter system(PCS)control system containing high-order time-delay links,focusing on the problem that it is difficult to take into account the time-domain and frequency-domain performance indicators in pa-rameter design,a multi-objective visual design method based on the D-partition method is proposed.Firstly,the sys-tem爷s stable boundary is drawn.Then,the three-dimensional diagrams of the time-domain and frequency-domain per-formance indicators varying with the parameters are drawn separately.Finally,multi-objective optimization is carried out in a unified coordinate system,which further improves the dynamic and static performance of the system.This method has the property of intuitiveness and clarity,without the need for repeated trial and error,and the simulation and ex-periment prove the effectiveness of this method.
