Principle of automatic control can make the controlled object in no one directly involved in the case according to the scheduled law operation.
基於此思想，本設計最大限度的實現系統的自動化，通過傳感器來對系統進行控制。
Based on this thought, this design realize the maximum system automation, through the sensor to control system.
為了實現對基於自由擺的平板的控制,建立基於自由擺的平板控制系統。
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轉角與自由擺轉角的關系,推導出關系式,再對控制單元、反饋單元進行分析比較給出方案。
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.
系統的控制部分以STC12C5A60S2單片機(MCU)為核心，利用從擺桿上的傳感器采集的數據來輔助單片機控制步進電機(step motor)的轉動，實現由高精度的角度傳感器測量出擺動角度後由步進電機控制的平板在周期擺動中做相應反饋調整,然後在現有器件的基礎上編制出控制軟件,在設備上進行調試,最後對系統的精度進行分析並進行實際測量。
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.
