"基于STM32的直流电机PID调速系统设计与实现"

基于STM32的直流电机PID调速系统设计中，电机转速控制是至关重要的。本设计以PID为基本控制算法，利用STM32F103单片机作为控制核心，通过产生受PID算法控制的PWM脉冲实现对直流电机转速的精确控制。同时，通过光电传感器将电机速度转换成脉冲频率反馈到单片机中，实现转速闭环控制，达到转速无静差调节的目的。该系统还采用320×240TFTLCD显示器作为显示部件，通过4个按键通过界面切换方式设置P、I、D、V四个参数和正反转控制，并可以通过显示部件了解电机当前的运行状态和系统的CPU温度。该系统具有非常高的控制精度和强大的抗干扰能力。 Motor speed control occupies a crucial position in the motion control system; in the design of the motor speed control for the study, PID is used as the basic control algorithm, and the STM32F103 single-chip microcomputer is used as the control core to achieve precise control of the motor speed by generating PWM pulses controlled by the PID algorithm. Additionally, a photosensitive sensor is used to convert the motor speed into pulse frequency and provide feedback to the single-chip microcomputer, thus achieving closed-loop control of the speed without static error. The system also uses a 320×240 TFT LCD display as the display component and 4 buttons for interface switching to set the P, I, D, and V parameters, as well as control the forward and reverse rotation. The display allows users to monitor the current operating status of the motor and the CPU temperature of the system. This system has high control accuracy and strong anti-interference capabilities.
