Multi-degree of freedom inertial sensor four-axis unmanned aerial vehicle autonomous navigation flight controller

Abstract

The invention discloses a multi-degree of freedom inertial sensor four-axis unmanned aerial vehicle autonomous navigation flight controller, which comprises a DSP arranged inside the unmanned aerial vehicle. A power supply module provides power for the DSP; the DSP is directly connected with the inertial sensor and an air pressure altitude sensor via a system bus to integrate the inertial sensor and the air pressure altitude sensor as a whole; the DSP is also connected with a wireless data transmission radio station and can communicate wirelessly with a ground station control system via the wireless data transmission radio station; the information output end of the DSP is connected with an electron speed regulator; and the electron speed regulator is connected with the motor of the unmanned aerial vehicle and can control the speed of the motor of the unmanned aerial vehicle. The multi-degree of freedom inertial sensor four-axis unmanned aerial vehicle autonomous navigation flight controller has the advantages that the processor is integrated with the inertial navigation sensor and an air data sensor and can perform data exchange; and due to the integrated design, the system-level serial communication is reduced, the inertial data updating rate is improved, the reliability of the system is enhanced, and the cost, the volume, the weight and the power consumption are reduced.

Description

technical field [0001] The invention relates to an unmanned aerial vehicle flight controller, in particular to a multi-degree-of-freedom inertial sensor multi-freedom inertial sensor four-axis unmanned aerial vehicle autonomous navigation flight controller. Background technique [0002] Quadrotor unmanned aerial vehicle is a six-degree-of-freedom vertical take-off and landing unmanned aerial vehicle, which can complete tasks that fixed-wing aircraft cannot complete, such as hovering, low-speed flight, vertical take-off and landing, and indoor flight. Compared with traditional helicopters, It also has the advantages of simple structure and control, low manufacturing precision requirements, good stability, and weak gyro effect. In recent years, quadrotor unmanned aerial vehicle has become an international research hotspot due to its many advantages and broad application prospects in fields such as unmanned investigation, traffic management, forest fire prevention, and urban pa...

AI Technical Summary

Problems solved by technology

[0003] (1) The architecture of the current flight control system is that the inertial navigation system, air data system, and flight control computer are designed separately and independently, and data is exchanged between each system through serial data communication, resulting in high cost, heavy weight, and volume. Large, low integration and low reliability

[0004] (2) The current flight controllers all use independent inertial sensor units, which cannot guarantee the orthogonality of the sensors
