摘要

本論文提出一種改良的控制方法，將模糊分數階次比例積分微分控制器與抗積分飽和功能結合，然後應用於全橋換流器。相較於整數階次比例積分微分控制器，分數階次比例積分微分控制器的積分項和微分項具有分數階次，可以增強整數階次比例積分微分控制器的動態和穩態響應。但在面對不確定性干擾時，分數階次比例積分微分控制器參數調整不易，難以達到預期的控制效果。因此模糊邏輯控制器被用來適當調整分數階次比例積分微分控制器的控制參數，以達到更優越的性能。同時，抗積分飽和功能與模糊分數階次比例積分微分控制器結合，以確保積分部分不會產生飽和，提高控制系統的穩定性。模擬結果顯示，所提出的全橋換流器無論是在電阻負載、步階負載還是非線性負載，都可以得到高品質交流輸出電壓。

This thesis proposes an improved control method with application to full-bridge inverters. The improved control method combines the fuzzy fractional-order proportional-integral-derivative (FFOPID) controller with an anti-windup function. Compared with the PID controller, the integral and derivative terms of a fractional-order proportional-integral-derivative (FOPID) controller possess fractional order, which can increase the dynamic and steady-state response. But in the face of uncertain interferences, it is not easy to adjust the parameters of the FOPID controller for achieving the desired control effect. Therefore, the fuzzy logic controller is utilized to appropriately adjust the control parameters of the FOPID controller to yield superior performance. Simultaneously, the combination of the anti-windup function and the FFOPID controller ensures that the integral part remains unsaturated, increasing the stability of the control system. Simulations demonstrate that the proposed full-bridge inverter can obtain high-quality AC output voltage under resistive loads, step loads, and nonlinear loads.
