Other available models are mostly code based differential equations which have less provision for modification and model expansion. This paper mostly emphasizes the theory behind quadrotor dynamic modeling and maneuver control. How Simulink ® can model and solve the 6-DOF equations of motion of a rigid body (building, solving, implementing equations, and incorporating the rotation matrix concepts along the way) How to linearize a 6-DOF model and design controllers for altitude and attitude control 2017-09-05 · This thesis considers the control of quadrotor using a linear PID control and ℒ1 adaptive control. In a justifiable concept, PID controller can be used to control a quadrotor, but in the presence of uncertainties or disturbance, the quadrotor can’t be automatically adjusted to control the changing dynamics of the quadrotor. In this paper, we develop a dynamic 6DOF model for a quadrotor that includes rotor blade ﬂapping, induced thrust due to forward ﬂight and climb, and aerodynamic drag. Unlike previous work, we allow the wind to vary from rotor to rotor, which is especially important for ﬂight in close proximity to another quadrotor.

Section III presents the proposed dynamic model for this study which holds . appropriate Quadrotor control requires an accurate model of the system. The first dynamic model of quadrotor was designed by Altug et al (2002) using Newton-Euler’s method.It was a linear model with only body dynamics, which had been derived from simple hypotheses (Altug et al., 2002). The first Lagrangian model of quadrotor was proposed and and Landing (VTOL) type Unmanned Aerial Vehicle(UAV) known as the quadrotor.

Chapter 5 shows the quadrotor simulator. It is a Matlab-Simulink program used to verify the correctness of the helicopter dynamic model and to test the control algorithm performance. The system structure, block implementations and 3D visualization are deepened to better explain the power of this tool.
