以可程式邏輯陣列為基礎之單晶片直流馬達控制器研製

FPGA-based Single-chip Controller for DC Motors

摘要


本文敘述以單晶片8051為核心結合了功能強大的可程式邏輯陣列(FPGA)元件XCS10,研製出可適用於直流馬達之控制器。在功能方面除具有八組AD轉換,一組DA轉換其輸出範圍可於10V以下任意調整外;另有八個D/I具光耦合器隔離雜訊、八個D/O除了光耦合器隔離雜訊外並有2803達靈頓放大、2位元之譯碼器、七段顯示器介面、485串列埠介面等。透 過可程式邏輯陣列內部程式的自由編修,使得該控制器具有脈寬調變(PWM)與電壓輸出,以作為直流馬達控制之目的。

In this study an FPGA-based single-chip controller for DC motors is developed. The controller contains 8 sets of A/D converters, one D/A converter whose output ranges from 0 to 10V, 8 D/I ports with photo couplers for isolation of disturbances, 8 D/O with 2803 Darlington amplifiers and photo couplers, a two-bit encoder, a 7-segment display, and a 485 serial interface. Through the flexible coding of FPGA, the signal-chip controller can output the PWM signal and voltage signal to control DC motors. Finally, the experiments show that the FPGA-based single-chip controller has excellent working performance.
