| 摘要: |
| 提出一种PI控制器参数的可视化整定方法。该方法直接依据系统传递函数模型，在（Kp，Ki）平面上绘制稳定边界曲线，判断并确定其稳定区域即稳定集；然后在稳定集中选取并绘制满足频域性能指标的控制参数集；最后在频域参数优化的基础上，进行满足稳态性能指标、动态性能指标、超调量和上升时间等时域性能的参数寻优，从而找到最佳的PI参数集。对CIGRE HVDC基准模型的仿真验证了该方法的正确性。 |

| Abstract: |
| A method to visually tune the parameters is given for PI controller. According to the transfer function model of system，the stability boundary locus is plotted on（Kp，Ki） plane and the stable region，i.e. the stable set，is determined，from which，the control parameter set satisfying the frequency domain performance index is selected and plotted. The time domain performance indexes optimization is then carried out to find the best PI parameter set，including steady-state performance index，dynamic performance index， overshoot，rising time，etc. The simulation of CIGRE HVDC Benchmark model verifies its correctness. |
