摘要
介绍一种基于NiosⅡ软核的直流电机PID控制系统。采用PWM直流电机调速方案,利用Altera公司推出的DE2板作为综合开发平台,采用SOPC技术,通过在FPGA中植入嵌入式软核NiosⅡ作为中央处理器,借助PID控制算法实现整个直流电机外围电路的PWM闭环调速控制,这是对直流电机经典控制(即基于单片机或DSP的电机控制)的全新改进。
A PID control system of DC motor based on soft-core Nios Ⅱ is introduced. The PWM DC regulating speed program is used, Altera DE2 board is adopted as the integrated development platform, SOPC technology is used to embed soft-core Nios Ⅱ in the FPGA as central control device, PID control algorithm is adapted to control the PWM closed loop speed control of the entire peripheral circuits. This method is a different way from traditional motor control（DC motor based on SCM or DSP）.
