直流电机的控制一般采用单片机或DSP作为核心控制器,集成度较低并且稳定性较差。文中介绍了一种基于Nios Ⅱ软核处理器的直流电机控制系统。利用SOPC平台设计并封装了PWM模块,在FPGA内嵌入Nios Ⅱ软核作为微处理器,借助光电编码器实现电机测速反馈。同时,采用数字PID算法实现对直流电机的PWM闭环调速控制,并最后对数字PID算法进行改进。实验表明,改进后控制系统的动态性能得到了很大的改善,而且整个系统的设计简单,集成度高,系统稳定,同时也在实际的应用中得到了验证

DC motor control generally uses the microcontroller or DSP as the core controller,which is less integrated and less stable. A DC motor control system based on soft core Nios Ⅱ is proposed in this paper. The PWM module is designed and packaged on SOPC ;The soft core Nios II is embed into the FPGA so it can work as a microprocessor;Photoelectric encoders are used to measure motor speeds. At the same time, the digital PID algorithm is used to achieve the PWM closed-loop DC motor speed control, which is improved finally. Experiments show that improved control system dynamic performance has been greatly improved, and the whole system design is simple, highly integrated, system stability, but also in practical application has been verified
