摘　　要：关于电机的仿真控制有多重方法及手段,电机控制最早采用模拟比例-积分-微分(PID)的形式,对其具体关键参数进行设定后,整个传动系统在运行过程中便不再改变。近年来,数字PID得以快速发展,除达到基本的控制要求外,PID技术更具有灵活的可控性及可靠性。本次设计以PID为主要控制算法,单片机为控制器,产生由占空比控制的脉宽调制(PWM)技术波信号,进而对电机进行操控,组成位移随动系统。此外,利用霍尔传感器进行信号转换,将速度转换为波信号并通过控制系统反馈机制反馈至控制器,以此来检测电机的转速。There are multiple methods and means for the simulation control of the motor,the control of the motor is the earliest in the form of analog proportional integral derivative(PID),after setting its specific key parameters,the entire transmission system will no longer change in the process of operation. In recent years,digital PID has been rapidly developed,in addition to meeting the basic control requirements,PID technology is more flexible controllable and reliable. This design takes PID as the main control algorithm and the micro-controller as the controller to generate the pulse width modulation(PWM)wave signal controlled by the duty cycle,and then manipulate the motor to form a displacement follower system. In addition,a Hall sensor is used for signal conversion,converting the speed into a wave signal and feeding it back to the controller via a control system feedback mechanism to detect the speed of motor.
