| 摘 要： | 以TI公司的超低功耗MCU LM3S811单片机为核心控制器,设计并制作了一个LED点光源自动跟踪系统.LM3S811计算出位置误差后,采用PI控制算法处理,以驱动减速电机跟踪点光源.经过实际场景测试,当点光源支架沿着圆周和直线缓慢平稳移动限定的角度和距离时,该系统均能使激光笔在左右和上下移动方向上快速、连续地实现LED点光源的跟踪.

| Abstract: | LED point source automatic tracking system is designed by using MCU LM3S811 single-chip microcomputer with super low power consumption as the core controller which is produced by TI Company.LM3S811 calculates the position error,which is subsequently handled by PI control algorithm to drive the reduction motor to track the point source.Tests show that the system can make the laser pen move in all directions quickly and continuously to realize the tracking of the point source when the point source moves slowl... |
