摘要
介绍了一种小型雕刻机低成本实现闭环控制的方案,通过在运动部件上固定同步带一端,编码器输入轴上安装同步轮,同步带与同步轮啮合实现传动,从而实现编码器对运动部件的位置信息检测的方法实现反馈。通过主控单片机的程序算法根据编码器信息对步进电机进行实时调节从而实现闭环控制,最终可以以低成本实现闭环控制。相比于行业上常用的光栅尺和磁栅尺作为位置检测传感器,与伺服电机组成闭环控制的方式,所介绍的闭环控制方案在成本上有极大的优势。
The low cost closed-loop control program for a small engraving machine is introduced in this paper. Synchronous belt and synchronous wheel complete gear transmission Based on the moving parts and fixed belt is installed on the shaft encoder input synchronous wheel. So as to realize the feedback method of detecting position information of the moving parts of the encoder. Through the program the mierocontroller control algorithm according to the encoder information to the stepper motor control to achieve real-time closed-loop control, the final closed- loop control can be achieved at low cost. Compared to the industry commonly used grating and magnetic grating as a position detection sensor, and servo motor closed-loop control method, the closed-loop control scheme introduced here has great advantages in cost.
