摘　　要：以TI公司的MSP430F5438单片机为控制核心,结合步进电机和精密电位器WDD35D-4,实现了基于自由摆的平板控制与激光追踪系统。当摆杆摆角为45°～60°时,平板可以承载8枚一元硬币,并在5个摆动周期内维持稳定;当摆杆摆角为30°～60°时,固定在摆杆平板上的激光笔可以在15s内找到并跟踪1.5m远处的靶心。Taking TI MCU MSP430F5438 as the control core, combining stepping motor and precision potentiometer WDD35D-4, a flat precise control and laser tracking is realized based on free pendulum. When the pendulum angle is between 45 and 60 degrees, the plate can carry eight one-yuan coins and maintain stability in 5 swing periods. When the pendulum angle is between 30 and 60 degrees, the laser pen fixed on the pendulum flat can find and track the target 1.5 m away in 15 s.
