摘要
针对直流电机速度与位置的精确控制问题,提出以STC8系列单片机为控制器,结合驱动器、直流电机、编码器构成闭环系统,分别采用位置式和增量式PID控制算法,通过对比例、积分、微分环节参数的调节,实现对电机转速与位置的控制。设计中将位置式和增量式PID控制算法以C语言模块化形式进行编写,在使用过程中只需传递其相关参数,方便程序的移植及参数修改。实验证明,该方案能实现对电机转速和位置的稳定控制,且具备控制精度高的优点,对于位置式和增量式PID控制系统的设计有一定的指导意义。
Aiming at the precise control of speed and position of DC motor,the STC8 series microcontroller is used as the controller,combined with the driver,DC motor and encoder to form a closed-loop system,and the position and incremental PID control algorithms are adopted to realize the control of motor speed and position by adjusting the parameters of proportional,integral and differential links.The design of position and incremental PID control algorithms is modularized in C language,and only the relevant parameters need to be passed in the process of use,which is convenient for program transfer and parameter modification.The experiment proves that the scheme can achieve stable control of motor speed and position,and has the advantage of high control accuracy,which has certain guiding significance for the design of position and incremental PID motion control system.
