自动控制原理可以使被控对象在没有人直接参与的情况下按预定的规律运行。 Principle of automatic control can make the controlled object in no one directly involved in the case according to the scheduled law operation. 基于大握虚此思想，本设计最大限度的实现系统的自动化，通过传感器来对系统进行控制。 Based on this thought, this design realize the maximum system automation, through the sensor to control system. 为了实现对基于自由摆的平板的控制,建立基于自由摆的平板控制系统。 In order to realize the free pendulum based on the plate control, established based on free pendulum's flat control system. 本文首先分析平板的控制转角与自由摆转角的关系,推导出关系式,再对控制单元、反馈单元进行分析比较给出方案滚燃。 This paper firstly analyzes plate control Angle with the free pendulum Angle relationship, deduced relation, again to control unit, feedback unit carries on the analysis comparison given scheme. 系统的控制皮缓部分以STC12C5A60S2单片机(MCU)为核心，利用从摆杆上的传感器采集的数据来辅助单片机控制步进电机(step motor)的转动，实现由高精度的角度传感器测量出摆动角度后由步进电机控制的平板在周期摆动中做相应反馈调整,然后在现有器件的基础上编制出控制软件,在设备上进行调试,最后对系统的精度进行分析并进行实际测量。 System control part to STC12C5A60S2 microcontroller (MCU) as the core, USES from pendulum bar on the sensors to collect data to assist single-chip microcomputer control stepping motor (step motor) rotation, realize the high precision of Angle sensor measure the swing Angle by stepping motor control plate in the periodic oscillation in the corresponding feedback adjustment, then on the basis of the existing devices formulate control software, on the equipment debugging, and finally to the precision of the system analysis and practical measurement. 关键词：单片机； Keywords: SCM; 自由摆； Free pendulum; 平板控制； Flat control; 角度传感器； Angle sensor; 步进电机 Stepping motor
