%X 直流电机调速技术是工业自动化领域中非常重要的技术之一，具有广泛的应用前景和市场需求。本项目我们用到的微控制器是AT89C51型号单片机，并利用PWM脉冲宽度调制的方法设计出来的一个直流电机调速系统。AT89C51单片机作为系统的核心芯片，电机驱动电路则是用到L298N来进行控制的，通过与单片机各引脚的相互连接，实现了一个用PWM来控制的直流电机调速系统。使用proteus 8对系统进行电路的设计与仿真，并利用Keil5来进行程序的编写，最后通过proteus 8与Keil 5的联合仿真与测试从而实现电机调速系统的功能。<br />
DC motor speed regulation technology is one of the most important technologies in the field of industrial automation, with broad application prospects and market demand. The microcontroller used in this project is an AT89C51 microcontroller, and a DC motor speed control system is designed using PWM pulse width modulation method. The AT89C51 microcontroller is the core chip of the system, and the motor drive circuit uses L298N for control. By connecting with each pin of the microcontroller, a DC motor speed control system controlled by PWM is achieved. Use proteus 8 to design and simulate the circuit of the system, and use Keil 5 to write the program. Finally, through the joint simulation and testing of proteus 8 and Keil 5, the function of the motor speed control system is achieved.
