Study On Small Multi-rotor UAV Flight Controller

Multi-rotor is a hot and front issue of domestic and foreign researches in recentyears, and have wide applications in agriculture,commerce and defense.This paperstudies the characteristics of small electric multi-rotor, the similarities and differencesof control methods between the various structures, designed a generic multi-rotor flightcontroller hardware platform.According to the system requirements and concept of modular design, the paperproposed generic multi-rotor flight controller hardware platform construction, selectedthe microcontroller chip, all kinds of sensors. Besides, the paper discuss the connect ofvarious modules and the design of circuit. Also, the paper completed the circuit of eachmodule, including external ROM, gyro, altimeter, power diver circuit and compass andthe PCB of the hardware platform.Finally,we test the flight controller hardware, including static tests and dynamictests. The test results are given to verify the feasibility of generic flight controllerhardware.
