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.

Energy Shaping Controller for a Revisited Quadrotor Model Using New Passive Outputs Abstract: This article proposes a new control algorithm to solve the regulation problem for a quadrotor vehicle using the passivity-based control method, without solving partial differential equations neither performing a partial dynamic inversion. 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.

## 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. Lower level control systems will run at a high rate and control the quadrotor’s attitude. These controllers rely on the onboard IMU measurements.

In In this paper, the model of a quadrotor with quadrotor DJIF450 frame has been established using Newton Euler but with empirical parameter identification. In this method the parameters are found using a custom test rig. Unlike many of the published models, less parameters are assumed.

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. Lower level control systems will run at a high rate and control the quadrotor’s attitude. These controllers rely on the onboard IMU measurements. 2012-01-01 2014-01-01 In this thesis a mathematical quadrotor model based on cascade modeling theory, using a passivity-based control solution is derived and presented.

This paper addresses the problem of damping vibrations of a cable-suspended payload during positioning of the quadrotor. A nonlinear model is derived for the coupled quadrotor-pendulum system in the *X-Z* plane using Euler–Lagrange formulation. Sliding mode control (SMC) is used for horizontal positioning and payload vibration damping, while a feedback linearizing controller is
