摘　　要：常规的直流电机速度控制方法利用线性化机电动力学方程的传递函数获取控制模型,导致电机速度与参考速度存在控制波动。因此,设计了基于单片机PID算法的直流电机速度控制方法。利用单片机PID算法,构建出直流电机速度控制模型,对直流电机速度变化进行平稳地跟踪控制。建立直流电机速度控制平台,将直流电机速度变化数据进行准确分析,并利用预测函数对直流电机速度进行实时控制。采用仿真实验的方式,验证了在该控制方法下,直流电机速度与参考速度能够保持一致、控制效果更佳,能够应用于实际生活中。Conventional speed control methods for DC motors use the transfer function of linearized machine electrodynamics equations to obtain control models,resulting in control fluctuations between motor speed and reference speed.Therefore,a DC motor speed control method based on microcontroller PID algorithm was designed.Using the microcontroller PID algorithm,a DC motor speed control model is constructed to smoothly track and control the speed changes of the DC motor.And establish a DC motor speed control platform to accurately analyze the speed change data of the DC motor,and use predictive functions to real-time control the speed of the DC motor.By using simulation experiments,it was verified that under this control method,the speed of the DC motor can maintain consistency with the reference speed,and the control effect is better,which can be applied in practical life.
