Title Building of Rotor Unmanned Aerial Vehicle (UAV) Simulation Platform Based on Simscape Toolbox
Abstract
The Rotor unmanned aerial vehicle (UAV) has been developed since 1907, with the
rapid development of unmanned rotary wing aircraft, the relatively complete theory
and practice have been obtained up to now. Using aircraft simulation platform to
build an aircraft model can effectively improve the feasibility and accuracy of
UAV flight control system debugging and experiments, especially in the design and
analysis phase of the flight control systems, the use of aircraft simulation
platform to build simulation model of the whole process more economical
experimental study and flexible. And the rotorcraft simulation platforms built
with different software have been launched one after another. This paper is about
the four-rotor aircraft simulation platform built with Matlab. This simulation
platform has the following innovative designs: 3D hardware model of the aircraft
is built by use of Simscape toolbox, so as to easily observe the flight attitude
and control effect of the aircraft; Each parameter of the hardware model can be
adjusted, which can meet the control requirements of the different controller and
the actual situation; All the input and output ports are intuitive, so it is
convenient for the external connection of the controller.
