Cím:	Comparison of Direct and Inverse Model-based Disturbance Observer for a Servo Drive System / Nándor Fink, Guo Zenan, Péter Szemes, Péter Korondi
Dátum:	2023
ISSN:	1785-8860
Megjegyzések:	The well-known disturbance observer - which is based on the transfer function of the inverse model -, was published almost four decades ago. To practically implement the inverse of the transfer function a filter is added to it, in order to eliminate high frequency disturbance signals. A key step of the design of this Inverse Model Based Disturbance Observer (IMBDO) is the selection of the filter with appropriate parameters. This paper proposes a disturbance observer, which is based on direct model (DMBDO) and it can work without any additional filter. It simplifies the design and the implemented controller code. Discrete time implementations of IMBDO and DMBDO are compared by a simple internetbased servo system in a non-real-time control environment. The effect of non-equidistant sampling is examined.

Cím:	Bond-Graph-Based Approach to Teach PID and Sliding Mode Control in Mechatronics / Zenan Guo, Péter Korondi, Péter Tamás Szemes
Dátum:	2023
ISSN:	2075-1702
Megjegyzések:	The main contribution of this article is creating synergy between subjects; this means that students use the same graphical tool in several subjects. So far, the bond graph has not been used in control theory, but it is the "native language" of mechatronics engineers, so we would like to introduce it into the teaching of control theory. The bond graph method is proposed as a novel teaching method to teach mechatronics subjects in the paper. The bond graph is a graphical alternative to ordinary differential equations from a mathematical standpoint. Traditionally, control theory employs ordinary differential equations, as they are familiar to control theorists. However, mathematically, both approaches are equivalent but require a slightly different approach in their application. This article highlights the mathematical similarities between the two approaches while emphasizing the distinctions in graphical representation. Another contribution is that the PID and sliding mode controller are represented using the bond graph method. In the meantime, through the use of practical examples, we effectively illustrate how the same problem can be solved using either approach. In the training materials, the PID controller and an adaptive robust sliding mode controller (ARSMC) with the bond graph are utilized as examples to demonstrate synergy in mechatronics. Finally, we present proof that mechatronic engineers achieve superior outcomes when utilizing the bond graph approach, based on test results from undergraduate students.

Cím:	Bond graph-based teaching method to enhance the synergy of mechatronics in LabVIEW / Zenan Guo, Szemes Peter Tamas, Korondi Peter
Dátum:	2022
Megjegyzések:	Mechatronics is a hard interdisciplinary subject, which requires a tight synergy of mechanical and electrical knowledge. This paper presents a novel modular approach to teaching mechatronics subjects using the bond graph in LabVIEW. LabVIEW can provide an industrial environment that connects graphical and analytical aspects. The background of the mechatronics students is divided into two directions: mechanical and electrical. During the research, these two directions share a common part, which is the bond graph. The bond graph is a novel hybrid method to connect the mechanical and electrical parts. The bond graph is an efficient technology to teach mechatronics subjects, and it is easy to understand for the students. A modularity teaching method has been developed for undergraduate and master`s students at the engineering faculty, University of Debrecen. For the undergraduates, the focus is on the fundamental models, with the goal dedicated to applied technology and linear system. For the master`s stage, students will learn more complex controller systems because of the modular learning strategy that adds some modules to the basic models. A DC motor is modeled for the demonstration in the paper under the LabVIEW programming environment.
