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 [1]. The twelve states for the quadrotor are:

The OS4 quadrotor model described by Bouabdallah (Reference Bouabdallah 2007) is adopted. As shown in Figure 3, the simulation software includes the quadrotor dynamics and the Guidance, Navigation and Control (GNC) module. The MA-OIF, MA-IE and OIF are all realised for comparison. 2019-01-11 model of quadrotor UAV equipped with gripper, which is followed by section ‘‘Designing of control architec-ture’’ in which designing of control architecture is pre-sented, and the ‘‘Dual control approach’’ and dynamic effects of gripper are also discussed in this section.

I. INTRODUCTION In this paper, we propose models for a real quadrotor using ﬁrst principles and deep learning methods for the Multi-Step (MS) prediction task. Our proposed models can quadrotor’s on-board computer to control the vehicle in hovering ﬂight.

The quadrotor model – cannot accurately describe all phenomena in the flight environment, and so the performance of the tracking result may be degraded.

Abstract: This paper aims to present a comparison between various controllers to be used in dynamic model of a quadrotor platform. The controllers assumed in this work are conventional PID and a classic LQR controller.
