| 摘 要： | 采用带有自调整因子的模糊控制规则设计了有源滤波器直流侧电压的模糊控制器。为了简化系统设计,采用非均匀量化规则,并由直流侧电压的控制直接得到电源电流参考值,最后将模糊控制和PI控制相结合,构建了复合控制器。该控制器结合了PI控制稳态精度高和模糊控制鲁棒性强及自适应的优点。仿真和实验结果验证了该复合控制器在抑制电压超调、减小电流冲击、补偿谐波和无功电流等方面的有效性。

| Abstract: | A fuzzy controller for capacitor voltage at DC side is designed by using fuzzy control rule with self-adjusting factors.To simplify the system process, the non-uniform quantizing rule is adopted, and the reference current is regulated by the DC-link voltage directly. At last the fuzzy control is integrated with PI control to construct compound sectionalizing controller, which combines the merit of high steady state accuracy of PI control and that of good robustness and adaptivity of fuzzy control. The results from tests and simulation show that the overshoot of the system can be restrained in evident extent, the surge of current can be reduced, the reactive power and harmonic currents can be well compensated by using the compound controller. |
