摘要
为了实现平板的转动控制,完成硬币激光灯一系列操作,设计制作了一套基于自由摆的平板控制系统,实现了电机对自由摆系统中平板的状态控制。系统以Cortex-M3为核心,采用加速度传感器MMA7455完成对摆杆和平板的偏角测量,采用16细分的步进电机控制器,使用增量式闭环控制算法[1]实现步进电机精确控制,完成平板的转动控制。整个系统精度高,抗干扰能力强,实现了平板的转动、硬币的状态调整以及激光的投射控制。
To realize flat rotation control and accomplish a series of operations of a coin laser light, a flat control system based on free pendulum is designed, which realizes the flat control in a free pendulum system. The system takes Cortex-M3 as the core, and uses acceleration sensor MMA 7455 for the measurement of the deflection angle between the pendulum rod and the flat. It also adopts a 16-segment stepper motor controller, and uses an incremental closed-loop control algorithm[1] for the accurate control of the stepper motor and further the rotation control of the flat. The whole system has a high precision and strong anti-interference capability. It realizes the flat rotation, coin state adjustment and laser projection control.
