Adaptive models and online learning are two equivalent topics under different umbrellas of research – control systems and machine learning. This chapter will tackle one such application of a neural network-based model reference adaptive controller on a quadrotor unmanned aerial vehicle while stating the general principles behind each design decision so the knowledge can be generalized to

Quadrotor Model The quadrotor has four rotors which are directed upwards. From the center of mass of the quadrotor, rotors are placed in a square formation with equal distance. The mathematical model for the quadrotor dynamics are derived from Euler-Lagrange equations.

Why Quadcopter modeling and control? Quadcopters are a popular and relatively inexpensive platform to showcase Model Based Design Concepts of modeling, simulation and control can be applied to a variety of systems System highly unstable and difficult to control The quadrotor is an under-actuated device and therefore can describe the basic roll, pitch and yaw motions as well as movements in the Z-directions. It is, however, incapable of performing pure movements in the x and y directions without accompanying rolling or pitching movements. Modelling and Linear Control of a Quadrotor The third and last method feeds back the same variables as the second method but uses a simpler model for the rotor dynamics. Both PID and LQR techniques have been investigated with this model. The achieved performances were not always acceptable. In fact, only the third method model and the robustness of the control algorithms.

Quadrotor Description As shown in Figure 1, the quadrotor has four rotors to produce the propeller powers of 𝑖 = 1,2,3,4. Four rotors are two pairs (1, 3 and 2, 4). 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 achieved performances … model and the robustness of the control algorithms. Furthermore a 3D graphic output and a joystick interface made easier the testability and the observability of the system. A quadrotor platform was developed. The electronics was composed of a Micro Control Unit (MCU) interfaced with several devices: the power supply, the receiving These control systems are developed based on the quadrotor model derived in the System Modeling section, implemented in a simulated environment, and finally verified on an actual system.
