风力摆自动控制系统的设计及测试

Design and Test of Wind Pendulum Automatic Control System

以32位STM32F103ZET6单片机为核心,给出了风力摆控制系统的实现方案。系统由风力摆、MOS管全桥驱动、三维角度传感器和TFT彩屏等构成。为获取实测数据,设计了测试方案,完成了不同条件下的测试。测试结果表明,该系统在仅受直流风机动力控制下实现了风力摆快速起摆、画线、限时制动和准确画圆,以及风力影响后能够快速恢复画圆状态等功能,达到或超过了设计指标要求。系统具有人机交互友好、结构稳定、误差小的特点。该系统为四轴飞行器系统测试方案的确定、测试参数的选用、测试数据的分析等提供了借鉴。

Taking 32- bit STM32f103ZET6 microcontroller as the core,the implementation scheme of the wind swing control system is given. The whole system is made up of MOS tube full bridge driver,3D angle sensor and a TFT color display. To achieve measured data,the test scheme is designed and the tests under different conditions have been done. The test results show that when only controlled by DC Blower power,this system can realize fast swing,line drawing,limited- time brake,accurate circle drawing and the function that circle- drawing state restores quickly under the effect of wind,which meets or surpasses the design requirements and realizes suspension function at arbitrary positions. The system has such characteristics as friendly human- computer interaction,stable structure and small errors. Furthermore,it provides the reference for the scheme decision,parameter selection,analysis of test data of the axis aircraft system design.
