3D CAD model for a quadrotor system modeling and control

Abstract

The work focus on the advantages of several engineering software to present a case study for the quadrotor system by a used 3D CAD model. CAD model initially generated using one of the CAD software and it can be accessed from MATLAB software and converted into a virtual physical model. Quadrotors are unmanned aerial vehicles capable of vertical takeoff, hovering, and landing . Quadrotor is distinguished by its small size, flexibility, and maneuverability. CAD model for the quadrotor system in this study is used to show the capability of the 3D model implementation in modeling and control. The actual quadrotor device was converted from the real system to a 3D model. Also, the model is converted to SimMechanics for the sake of simulation. Two different control methods are used in this work to stable the motion of the quadrotor system. First adaptive controller. Second, PID controller. Simulation results show the model works fine with the controllers and it preserves the desired position and attitude along the desired predefined path. Results shown when a comparison was made that the ratio of error for PID controller is better.
