3D CAD model for a quadrotor system modeling and control

In this paper, 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. The 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. The quadrotor is distinguished by its small size, flexibility, and maneuverability. The small sensors and actuators used in these systems are effective enough in comparison with the larger systems. The CAD model for the quadrotor system in this study is used to show the capability of the 3D model implementation in modeling and control. These models echo on the real-time models to improve the behavior in the real world. 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 the adaptive sliding mode controller with the adaptive controller. Second the adaptive sliding mode controller with the PID controller. The simulation results show the model works fine with the controllers and it preserves the desired position and attitude along the desired predefined path. The results shown when a comparison was made that the ratio of error for PID controller is better.
