[Abstract]:The four-rotor aircraft is a kind of unmanned helicopter which can take off and land vertically and hovering in the air. All kinds of flying attitude can be realized through the four rotors.It has the characteristics of flexible operation, simple structure and easy control. It can be used in forest fire fighting, aerial reconnaissance, surveillance, aerial photography and other tasks.In order to meet the needs of laboratory team research, this paper aims to design a hardware experimental platform for a small four-rotor aircraft, and to establish the foundation for further research work of the team.The main work is as follows: 1) in order to meet the research needs of the laboratory team, the overall structure of the four-rotor hardware system is determined. According to the overall structure of the system, a flight control board with 32-bit processor STM32VET6 is designed.Three-axis electronic compasses and barometers, and some common interfaces such as IICI SPI Ole DU JTAG UART PWM, are extended to facilitate the extension of other functional modules on the flight control board.In order to reduce the influence of position sensor on the weight of four rotor, an electronic governor of sensorless brushless DC motor is designed.Including electronic governor hardware design and software design.The hardware design includes the hardware circuit design of electric regulation and the design and realization of PCB wiring board.The electric control software mainly includes brushless motor starting and commutation control. 4) the designed flight control board and electronic governor are tested. Finally, the test platform is tested.It includes system power supply test, attitude sensor test, flight control board input and output signal test, electronic governor test, four-rotor flight test, and analysis of test results to verify the rationality and feasibility of the design.The test results show that the designed hardware system works well and the four rotor can achieve the expected function.In this paper, the flight control board and electronic governor of the four rotor are designed, and the test environment of the four rotor is built, and the test experiment is carried out to verify the feasibility of the hardware design of the four rotor.It provides an experimental platform for the lab team to carry out the next research work.
