To achieve longer flight duration of the microaerial vehicles (MAVs) it is needed to optimize theirpropulsion system. A typical propulsion system of VTOL(vertical take-off and landing) MAV consist of the propellerBLDC (brushless DC) motor, motor controller and battery(typically Lithium based chemistry). All these parts of thepropulsion system can be optimized in a specific way. In thecase of the propeller, this can be done by the optimization ofstatic and dynamic thrust performance. The motorconstruction can be optimized by using lighter materials orstronger rotor magnets. As for the battery - alternativepower sources like solar panels, hydrogen fuel cells etc. maybe used. We are focusing on the optimization of the motorcontrol part. In this paper, we are presenting synthesis ofthe BLDC controller using the field oriented controlstrategy which promises better performance in thedynamical response of the propulsion system, lower powerconsumption and generally higher efficiency in comparisonwith the traditional six step commutation techniques
