摘　　要：本文介绍了由ATmega16和L298N构成的直流电机调速系统,该系统作为纸张抗张强度测试仪的子系统,其主要作用是通过改变电动机的转速和转向而改变移动横梁的运动方向及速度,以不同的运行速度对纸张试样加载,满足不同纸张材料试验的要求。文中详细介绍了AVR单片机中关于PWM调速的相关寄存器的设置,给出了硬件电路。设计了一个模糊PID控制器以实现对直流电机调速系统的控制,通过仿真实验证明,其具有较好的动态性能和控制效果。A kind of speed regulating system for DC motor composed of ATmegal6 microcontroller and L298N was described. As a subsystem for a paper tensile strength test machine,and its main role is change the direction and speed of beam by changing the speed and rotation direction of DC motor,and the setting of relative registers of PWM regulating speed in AVR microcontroller was introduced. The hardware circuit were given . The applicatioh of this fuzzy PID controller in speed regulating system for DC motor is completed. The experimental results show that this fuzzy PID controller has good dynamic performance and control effect.
