Development of measurement-based feedback on 3-D coil non-invasive transducer in UAV´s rotation gear control unit

To perform exactness control of unmanned aerial vehicles actuating mechanisms the control system must be supplied by devises providing precision definition of values of current operation factors of those mechanisms. As such devises can be developed or searched essential measurement transducers. This paper presents description of easy development of measured based feedback loop on the basis of proximity sensor having 3D-inductive coil as a sensitive element for measurement of rotation angle of elevator.
