摘要
在传统的增量PID控制算法的基础上,提出改良的PID控制算法.设计一种基于单片机控制的、低分辨率脉冲测速和脉宽调制(PWM)驱动的数字式闭环调速系统.系统的测速环节由UGN-3020霍尔传感器和电机主轴上的6孔圆盘组成,电机每转动一周可检测到6个检测脉冲,送入单片机的计数器计数,每0.2 s读取计数值,经计算可得电机的转速.系统具有无级调速、速度显示及较强的抗负载扰动能力,在控制精度要求不高的情况下,可以实现对速度的稳定控制.
Based on traditional increasing proportional-integral-derlvative （PID）, a refined PID is given. A digital close loop speed control system based on single chip computer with low resolution of speed testing pulse and pulse width modulation （PWM） driver is designed. The speed feedback structure is composed of UGN-3020 Hall sensor and six hole plate on the shaft. In every circle, six pulses can be received by the counter of the single chip computer which is read every 0. 2 s. The rotation speed of the motor can be calculated by the counting. The system possessed the ability of smooth speed adjusting, speed display and anti-disturbance of which speed can be stably controlled in the case of low precision demand
