| 摘 要： | 以单相逆变电源为研究对象,提出了一种在全论域范围内带有自调整因子的变间距模糊量化算法,并将其与PI控制结合构成模糊-PI双模控制器.该控制器综合了模糊和PI两种控制的优点.仿真结果表明,该控制器用于逆变电源,具有动态响应快、非线性负载下输出电压THD低、稳态精度高、系统鲁棒性强等特点.

| Abstract: | In this paper, variable interval fuzzy control arithmetic with self-adjusting factor is proposed, which aims at the single-phase inverter. The fuzzy-PI double mode controller is introduced, combined with fuzzy and PI. The proposed method combines the advantages of the fuzzy and PI which can be switched between two controlling mode according to the threshold. Simulation results shows that the controller can be used effectively in controlling the inverter providing fast dynamic response, low output THD with nonlinear load, nice static character- istics and strong robustness of system. |
