摘要
基于Proteus拥有齐全的元件库和强大的电路分析实物仿真功能,提出了用于步进电机闭环自动控制系统的方法。以AT89C52芯片为微处理器,L297和L298芯片驱动步进电机,利用光电编码器原理设计反馈电路,形成闭环。用C语言编程,设计扰动,模拟外界干扰,应用PID算法,利用LCD显示,比较设定值与反馈值,实现位置反馈闭环控制系统的仿真。
Proteus-based libraries have a full range of powerful circuit analysis and simulation of physical function, so we offered a way to the closed-loop stepper motor for automatic control systems. AT89C52 chip as microprocessor, L297 and L298 chip to driver stepper motor, using the principle of optical encoder to design feedback circuit and form a closed loop. To design the disturbance and simulate outside interference with C language programming. Applying PID algorithm and making use of LCD display to compare the value of setting and feedback to achieve closed-loop control system simulation of position leedback.
