基于TMS320F28069的无人机舵系统控制器设计与实现

摘要

本文设计并实现了一种基于TMS 320F28069的小型无人机舵系统控制器.取消了原机舵系统的模拟通讯方式,改用RS485接口与飞控计算机进行通讯.在分析舵系统工作原理基础上,基于TMS 320F28069控制精度高、功耗低、外设丰富的优点,进行了软、硬件结构的模块化设计.实验表明,本文设计的控制器可靠性强、稳定性好、控制精度高,可以消除外界干扰对舵系统的影响.%The UAV actuator controller based on TMS320F28069 is designed and realized.The controller abandons the analog communication mode of the original actuator system instead of the RS485 interface serves to connect the flight control computer and the actuator system.According to the working mechanism of actuator system,the modular design of the hardware and software is realized based on the TMS 320F28069with high control precision,low power consumption and rich peripheral devices.The experiments indicate the controller designed has such advantages as great stability,high precision and reliability.The ambient interference can also be eliminated with the controller.
