Modelling and analysis of a tricopter

Abstract

Unmanned aerial vehicles (UAVs) can generally be defined as a “device used or intended to be used for flight in the air that has no on-board pilot”. Tricopter is one such UAV. Here we present new results to compute the kinematic and dynamic analysis for a tricopter mini-rotorcraft. The orientation and control of tricopter according to the parametric equation is also shown. The transformation of all the parameters from one co-ordinate to another co-ordinate is done. It include body frame of reference and earth frame of reference. Hence mathematical modelling of the tricopter is done. The relation or dependence of position on the angular speed of motor/s is shown by plotting three dimensional position versus time graph in MATLAB by considering different cases. A well dimensioned and rendered CAD 3D model of the intended tricopter is designed in CATIA and further rendered in Autodesk Showcase.
