本論文提出一種新的調整脈波寬度的方法使用在PWM的寬度調整應用於數位再設計,並且利用可程式邏輯閘陣列(Field Programmable Gate Array, FPGA)將模糊控制器實現,具體的模擬與硬體實現步驟如下:
1. 使用模糊理論撰寫混合系統的控制器用於調整脈波的寬度。
2. 設計一個具有可切換正負和零輸出功能的PWM脈波產生器。
3. 利用基因演算法(Genetic Algorithm, GA)來調整模糊控制器的歸屬函數以及PWM脈波產生器的正負切換與零輸出條件參數。
4. 利用MATLAB之Simulink來模擬混合系統的輸出響應與原類比系統之輸出響應做比較。
5. 將已模擬調整好的模糊控制器利用DSP Builder工具改寫為硬體描述語言VHDL之後載入硬體FPGA。
完成以上步驟後,我們用電腦當作模擬受控體,利用硬體FPGA控制器來取代已完成模擬的模糊控制器,驗證我們提出調整脈波寬度的方法在數位再設計性能表現上的優越性與可行性。
The thesis proposes a new method to adjust the pulse width of PWM (Pulse Width Modulation) used in digital redesign and to realize fuzzy controllers in the FPGA (Field Programmable Gate Array). Following steps are the specific simulation and hardware implementation:
1. Use Fuzzy Logic to design a hybrid system controller to adjust the pulse width of PWM.
2. Design a PWM generator whose output can be switched to positive, negative and zero states.
3. Use GA (Genetic Algorithm) to adjust parameters of membership function in fuzzy controller and to switch positive-negative and zero-output parameters of the PWM generator.
4. Simulate and compare the output response of hybrid system with that of analog system in MATLAB/Simulink.
5. Rewrite fuzzy logic control algorithm with DSP Builder and download it into hardware FPGA.
After above mentioned steps are completed, we will use a computer as a simulation plant and utilize the hardware FPGA controller to implement the fuzzy logic control algorithm of completed simulation. This will validate the proposed benefit and feasibility of the method of adjusting pulse width in performance of digital redesign.
