Abstract:

Since the quadrotor is directly driven by the power system, the accuracy of the power system model is essential. This paper presents a novel approach to build an accurate model of the power system. The motor-propeller model, the electronic-speed-controller model and the battery model are integrated to design an overall control model of the power system based on voltage compensation. An experimental testbed is set up to carry out parameter identification for the model through experiments and data processing. The results show that the thrust produced by the model is in line with expectations. The power system based on voltage compensation can effectively improve the accuracy of control.
