Mathematical modeling of variable pitched electric power system on UAV

In order to carry out the research on precise kinetic performance and improved control regulation, a modeling method of variable pitched electrical power system equipped on UAV is presented. Firstly, the white box model of variable pitched electric power system is built based on component analysis. Secondly, a number of experiments are performed by the ground testbench to identify parameters of model. According to the results of identification, the simulation model of system is built. From the output comparison of simulation and the physical device, the accuracy of the established mathematical model in this paper is verified.
