I am a sophomore majoring in automation, and I want to learn the control system of UAV. Please give some advice from teachers and brothers ~

As a student majoring in automation, it may be difficult to do professional UAV research, because professional UAV research requires you to master aerodynamics, fluid mechanics and other professional knowledge, which is not included in automation professional courses. If you must be a professional drone, you need to study this knowledge hard and spend a lot of time and energy, so it is not recommended that you be a professional drone.

I suggest you start with the model airplane and study the control system of the model airplane UAV. For the fluid structure, dynamics analysis and kinematics analysis of UAV, we can refer to the master's or doctoral dissertations of Beihang University, China Southern Airlines and Xigong University, and directly borrow their analyzed and designed aircraft models to study. For some parameters of aircraft, you can directly use the data in their papers without doing it yourself. Of course, if you want to do your own research in this field, you can also refer to some professional books at home and abroad to learn this knowledge by yourself, and recommend several aircraft model analysis software, such as AVL and VLM. (There are many similar softwares in this respect, and I will only list the ones I have used). According to the size and shape of aircraft parts (refer to some parameters in aircraft dynamics and kinematics equations), the aerodynamic derivatives of aircraft can be calculated, and then the force on aircraft can be analyzed. For students majoring in automation, I don't recommend that you spend too much time and energy in the above aspects.

For students majoring in automation, your advantages in UAV research lie in control algorithm, signal processing, host design and so on. Common control algorithms include PID control, fuzzy control and optimal control. These are all learned in your professional courses, so I won't go into details here. In this respect, we can do some research on attitude self-stabilization technology of UAV under small disturbance. Signal processing includes signal screening, denoising and information fusion. Because UAV uses a large number of sensors to collect all kinds of attitude information and flight information of aircraft, there is a lot of research space in signal processing, and there are a lot of literatures in this field at home and abroad. You can screen the directions you are interested in for research. To put it bluntly, the upper computer design here is to design a ground application software, so that the ground operators can intuitively see all kinds of flight information during the flight of the drone through the computer screen, record and even directly control the flight state of the drone, which requires some upper computer design software (such as labview is very good) and database knowledge. Of course, you need to write some code. You can use some programming languages such as C, C++ and C#. You can choose the language you are good at to write.

In addition to the above aspects, you can also study UAV formation control, UAV multi-sensor information fusion, and UAV wireless data. You can choose according to your own situation.

Finally, it is necessary to mention that UAV control is a very complex technology, which requires all aspects of knowledge. Any aspect is enough for an undergraduate or even a graduate student to complete the graduation project, so don't be greedy, choose the direction that suits you best, persevere, and eventually learn something useful. I hope these can help you. Good luck to year of the snake. ...
