| 为了弥补步进电机在开环控制中转速变化时容易发生堵转或过冲等一系列不足，采用测速模块对步进电机转速进行实时检测形成闭环控制，同时加入阶梯运行规律速度控制方法。阶梯运行规律实现使用单片机定时器设制给定脉冲频率的时间间隔，升速时脉冲串逐步加密，减速时脉冲串逐步稀疏。算法方面采用经典控制理论增量式PID控制算法来优化步进电机的输出特性。通过大量实验数据证明，设计的闭环调速系统可以提高步进电机的平稳性，达到了测试研究目的。 |

| In order to make up for shortcomings of blocking or overshoot of the speed change of stepper motor in open loop control, the speed of the step motor was measured by the measuring module, and the closed loop control was formed in the system. The speed control method of step motion law was added. The implementation of step motion law was to set given pulse frequency interval by using the microcomputer timer, and the pulse train was gradually encrypted when raising, and the pulse train was thinning when decelerating. The output characteristics of stepping motor were optimized by using the classical control theory incremental PID control algorithm. The results show that the design of the closed loop speed regulating system can improve the stability of the step motor and achieve the test results. |
