研制一種以FPGA 為核心、適用于多種直流電機(jī)的控制器。由單片F(xiàn)PGA 完成電機(jī)驅(qū)動波形發(fā)生、閉環(huán)控制運(yùn)算和上位機(jī)通信功能。該控制器既可以獨(dú)立進(jìn)行電機(jī)調(diào)速，也可以配合上位機(jī)進(jìn)行控制，在實(shí)時(shí)性和抗干擾性能方面優(yōu)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(yán)寒等特殊環(huán)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.
