在遥感过程中,要用稳定平台补偿飞行载体的姿态变化,以达到使相机垂直对地的目的。本文简要介绍了稳定平台的组成;分析了模糊算法和PID算法的控制优势;详细叙述了以微机械陀螺为反馈传感器,以TI公司的电机控制DSP芯片TMS320LF2407为控制器核心的控制系统软硬件设计与实现。结果表明,系统具有较好的稳定性和较高的精度,满足遥感平台的基本要求。
In the process of remote sensing, a stable platform should be used to compensate the attitude change of the flight carrier so as to make the camera perpendicular to the ground. This article briefly introduces the composition of the stable platform; analyzes the control advantages of the fuzzy algorithm and the PID algorithm; describes in detail the hardware and software design of the control system which uses the MEMS gyroscope as the feedback sensor and takes TI’s motor control DSP chip TMS320LF2407 as the controller And achieve. The results show that the system has good stability and high accuracy, and meets the basic requirements of remote sensing platform.
