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.}, keywords = {IDENTIFICATION; IDENTIFICATION; PERFORMANCE; sensors; MATLAB; MATLAB; Closed loop control systems; Control simulation; Simulink; Simulink; Simulink; Noise power; Closed-loop control; Closed-loop control; Sensor selection; mechatronic systems; Sensor parameter}, year = {2024}, eissn = {2211-0992}, pages = {107-117}, orcid-numbers = {Gincsainé Szádeczky-Kardoss, Emese/0000-0002-7789-6402} } @article{MTMT:34822034, title = {Equivalent Control of a 2D Crane and a 2D Drone Using Exact Linearization Based on Differential Flatness}, url = {https://m2.mtmt.hu/api/publication/34822034}, author = {Finta, Barnabás and Kiss, Bálint}, doi = {10.1007/978-3-031-51085-4_12}, journal-iso = {MECHANISMS AND MACHINE SCIENCE}, journal = {MECHANISMS AND MACHINE SCIENCE}, volume = {154}, unique-id = {34822034}, issn = {2211-0984}, abstract = {This paper presents the exact linearizing trajectory tracking control of two underactuated mechatronic systems, namely a 2D crane and a 2D quadcopter. 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.}, keywords = {CONTROLLERS; Nonlinear control; State feedback; Trajectories; Controller structures; Non linear control; Exact linearization; Feedback linearization; drones; rope; cranes; crane; Quadcopter; Quadcopter; differential flatness; Trajectory tracking control; Coordinate transformations; Equivalent control; Flat output; Underactuated mechatronic systems}, year = {2024}, eissn = {2211-0992}, pages = {131-141} } @article{MTMT:34717230, title = {A torziós ingák jelentősége Eötvös Loránd születése után 175 évvel}, url = {https://m2.mtmt.hu/api/publication/34717230}, author = {Völgyesi, Lajos and Szondy, György and Tóth, Gyula and Fenyvesi, Edit and Kovács, Péter Gábor and Kiss, Bálint and Égető, Csaba and Barnaföldi, Gergely Gábor and Lévai, Péter and Ván, Péter}, journal-iso = {MAGYAR TUDOMÁNY}, journal = {MAGYAR TUDOMÁNY}, volume = {185}, unique-id = {34717230}, issn = {0025-0325}, abstract = {Eötvös Loránd 1848. július 27.-én született, így 2023-ban ünnepeljük a születésének 175. évfordulóját.

The paper reveals promising results for an effective combination of nonlinear Kalman filters and the LPV framework.
