Method for synchronised control of electric motors of a remote controlled rotary-wing drone such as a quadricopter

摘要

The method involves establishing asynchronous series communication connection between a central controller (10) and microcontrollers (21-24). A message is sent simultaneously over connection lines (11, 12, 13, 14) for the central controller, where the message contains instructions specified by an address parameter of the receiving microcontroller to execute instructions. Each instruction is taken and executed for the receiving microcontroller. The instruction is chosen from a speed set point applied to an electric motor, request concern with data relative to operation of the motor or request concern with data relative to maximum operating speed of the motor.
