STM32基于PID算法的四旋翼导航系统设计+C程序

摘要：随着控制理论逐渐成熟和微处理器的性能的不断提高,本来难以实现稳定飞行的四旋翼飞行器又重新出现在人们的视野之中。本文在分析主流的四旋翼飞行控制和导航系统的基础上，设计了一款嵌入式四旋翼导航系统，可实现安全、半自主、稳定、易控的飞行操作。本设计采用STM32控制器作为导航微处理器，通过外围传感器信号处理和惯性导航相结合，模拟遥控PWM信号输出来控制飞行控制器，可做出定高悬停，自主飞行等动作，并能够通过软件，来切换遥控模式和自动飞行模式。43067

Four Rotor Navigation System Design Based on PID

Algorithm

Abstract: Since twentieth Century, with the development of control theory, and the microprocessor is difficult to achieve stable control of the four rotor aircraft and

reappear in people's field of vision. This paper is based on the analysis of the mainstream of the four rotor navigation system on the market, the design of an embedded four rotor navigation system. To achieve the four rotor aircraft safety, semi autonomous, stable, easy to control the flight operation. In this paper, the design of STM32 controller is used as the navigation microprocessor. Through the peripheral sensor signal processing, make the emergency stop, autonomous flight, through the communication serial port and flight controller communication, realize the combination of navigation and inertial navigation control. Can through the software, to switch the remote control mode and automatic flight mode, to achieve take-off and landing autonomous flight, so that the controller is more easy to get started.
