摘要
本文探討一個以交流截波器為基礎的加壓馬達控制方法，使得單相感應馬達輸出功率有調整的功能，然後控制泵浦讓管路壓力保持恆定。硬體架構使用交流截波器(AC Chopper)，藉由脈寬調變技術(PWM)，控制輸入感應馬達交流電源的電壓，依泵浦排水壓力(Pressure)來設定馬達輸出功率，過程將離心泵浦與感應馬達模型化，輔以PI數位控制器，透過Matlab simulink模擬驗證，最後實作交流截波器與相關電路，使用單晶片dsPIC33FJ16MC102來撰寫控制程式，讀取壓力感應器(SENSOR)傳回水的壓力值，進而控制馬達無段的改變輸出，實現泵浦加壓機能維持壓力於恆定值。

This paper explores an architecture and method that allows the signal-phase induction motor with a power regulating function, to control the pump with a constant pressure. The hardware architecture uses an AC chopper to control the input voltage of the AC power supply of the induction motor via pulse width modulation (PWM), and to set the motor output power according to the pump pressure. In detial, the models of centrifugal pump and induction motor are derivated. Next, the PID digital controlleris realized by simulink simulation. Finally, the AC splitter and related circuits are implemented, The single-chip dsPIC33FJ16MC102 is used for developing control procedures, and returning date of the pressure sensor. The AC motor is controlled to change the output of mechine power and achieve the pressure control of pump.
