I am currently working on a master’s thesis in which I am comparing the methods of controlling the motors of quadcopter. The main part of my thesis is about flying with PWM, DroneCAN and Cyphal.
I need a statistic on how often Cyphal/DroneCAN/PWM is used in drones to control motors so I can include it in my literature review. If anyone has it, or can tell me where to find it, I would be very grateful.
I expected to find few papers on Cyphal/old UAVCAN as they are more complicated to implement and most papers will be on PWM. As a result, it was funny that extensive literature reviews tried to assure me that there is only one way to control motors (via PWM)
