Several sensor parameters (such as noise power or delay) are simulated and their effects on the whole system’s performance are analyzed. For the simulations, Matlab-Simulink environment is applied. The simulated data are then used to estimate the transfer function of the whole closed-loop system with a controller. The services of the System Identification toolbox are appropriate for this task. If the specifications are given as the required damping and bandwidth of the system, the tool estimates the sensor parameters, which can ensure the desired performance. Some simulation results demonstrate the workflow of our tool, which was implemented using the App Designer of Matlab. © The Author(s), under exclusive license to Springer Nature Switzerland AG 2024.

This method is based on differential flatness, and it is shown that in the case of these two systems the controller structure is extremely similar down to a coordinate transformation. The flat outputs are the coordinates of the load and the coordinates of the center of mass of the body for the crane and quadcopter respectively. The resulting controllers both have two internal states, meaning that exact linearization is only achievable by dynamic state feedback. The reference trajectories need to be sufficiently smooth meaning that they have to be four times differentiable w.r.t. time. This intuitively means that the load of the crane can be thought of as a drone moving in the 2D plane. The force form the rope is equivalent to the thrust force generated by the propellers of the quadcopter. The same can be said about the rope angle and the orientation of the drone body. The presented control algorithm is validated using simulations, where the equivalence between the trajectories of the two systems is well observable. © The Author(s), under exclusive license to Springer Nature Switzerland AG 2024.

A dual quaternion is a compound of a unit quaternion and a translational vector, using the dual number formalization, such that the real part represents the rotation and the dual part, the translation transformation. Since the unit dual quaternion can be used to represent the rigid body dynamics in the 3D space, then the error dual quaternion can be used to design feedback control laws for both set-point stabilization, and attitude and position tracking. Simulation results using a rigid-body model are presented to show the performance of the dual quaternion formalism for simultaneous attitude and position control. © 2024 IEEE.
