摘要
介绍了由TMS320F28027和L298N模块以及编码器组成的悬挂运动控制系统。该系统通过控制2个步进电机,控制轴上线的收放来达到使悬挂物在平面内任意运动的效果,以实现画圆或指定图案和显示当前坐标等功能。主要介绍了步进电机的控制算法和利用TMS320F28027芯片实现位置闭环控制的方法。该系统具有高效、稳定、准确等优点。
The suspended movement control system which is consist of TMS320F28027, L298N module and absolute rotary encoder. The system simultaneously controls two step motors to move freely in a plane surface by rolling the line of the step motor ＇s control shaft, and it achieves the function of circling ~ drawing specified patterns, displaying the current coordinates, and so on. This paper focuses on the exploration of the control algorithms under control and the way to conduct the chip TMS320F28027. The system has the advantages of stability, efficiency and accuracy.
