研制一種以FPGA 為核心、適用于多種直流電機的控制器。由單片FPGA 完成電機驅動波形發生、閉環控制運算和上位機通信功能。該控制器既可以獨立進行電機調速，也可以配合上位機進行控制，在實時性和抗干擾性能方面優于MCU/DSP 控制器。該控制器的軟核可以在不同硬件平臺間移植，更換不同檔次的器件即可工作于輻射、高溫和嚴寒等特殊環境中。

Abstract:A FPGA-based controller is developed for various DC motors. The single FPGA chip implements the PWM wave generation, closed velocity loop, and communication with upper-controller. The controller can work independently or cooperate with upper-controller for driving DC motors. The performances of the controller are better than those of conventional controllers based on MCU/DSP in real time controlling and anti-jamming. Its soft IP core is easy to transplant between different hardware platforms. If we select appropriate level devices, this controller can be applied to some special fields, such as radioactivity, very high or low temperature.
