Controller design for variable pitch propeller propulsion drive

This article describes the structure of variable pitch propulsion drive controller (VPPDC) and its capabilities. The control algorithm is applicable for multirotor flying platforms with variable pitch propellers installed. The VPPDC is an extension of standard propulsion drive which improves its efficiency and extends the flight time. The algorithm is based on knowledge of accurate propeller and brushless motor properties. Its structure is described in Simulink.
