Design and Implementation of Powered Parafoil System Based on FreeRTOS

摘要

In order to meet the low cost and high performance requirements of the powered parafoil system, a multi-task, multi-priority real-time embedded powered parafoil control system is designed. The hardware platform of the system consists of the microcontroller STM32F407 of the Cortex-M4 kernel and the microcontroller STM32F103 of the Cortex-M3 kernel, the software platform consists of the FreeRTOS real-time operating system and the ADRC algorithm. The system realizes the functions of real-time multi-task autonomous flight and remote control flight. In this paper, the hardware platform and software platform of the system are introduced in detail. Experiments of simulation show that using FreeRTOS to perform real-time multitask management of the powered parafoil system can make full use of CPU resources and improve the stability and real-time performance.
