臺灣博碩士論文加值系統

本論文研製基於區間二型多項式模糊控制系統之三相雙向換流器，以微控制器Renesas RX62T為系統核心，藉由周邊電路與類比/數位轉換電路迴授系統各項參數值至區間二型多項式模糊控制器，計算後求得相應區間的功率開關責任週期比，本系統可操作於市電併聯模式與整流模式。本文首先推導以兩項調變為基礎之三相換流器狀態方程式，接著根據Lyapunov穩定理論，推導具抗干擾能力之區間二型多項式模糊控制系統平方和(Sum of Square, SOS)型式的穩定定理，控制器根據平行分布補償法設計，並以SOS Toolbox求解控制器增益。最後，以實測驗證其控制性能。

A three-phase bidirectional inverter based on interval type-2 polynomial fuzzy control systems is designed and implemented in this thesis. The microcontroller Renesas RX62T is implemented as the system core. The systems parameters are feedbacked to the interval type-2 polynomial fuzzy controller via peripheral circuits and analog-to-digital converter (ADC). After calculations, the duty ratios of power switches in corresponding interval are obtained. This system can be operated in grid-connected mode and rectification mode. In this thesis, the state equation of three-phase inverter is first derived from two phase modulation (TPM). Next, the sum of square (SOS) type stability equation of the interval type-2 fuzzy control system with disturbance suppression is derived according to the Lyapunov stability theorem. The controller is designed based on the parallel distributed compensation(PDC) method. And the controller gain is solved by the SOS Toolbox. Finally, the control performance is verified by experimental results.
