Mechatronic design requires that a mechanical system and its control system be designed as an integrated system. In order to make proper choices early in the design stage, tools are required that support modeling and simulation of physical systems -together with controllers-with parameters that are directly related to the real-world system. The 20-sim software, developed at the Control Laboratory of the Drebbel Institute is such a tool. Components in various physical domains (e.g. mechanical or electrical) can easily be selected from a library and combined into a process that can be controlled by block-diagram-based (digital) controllers. A few examples will be discussed that show the use of such a tool in various stages of the design. The examples include a typical mechatronic system with a flexible transmission, a mobile robot, and an industrial linear motor with a neural-network-based learning feed-forward controller that compensates for cogging.
Design, Control and Applications of Mechatronic Systems in Engineering
2017
Essential part of a mechatronics system is the measurement system that senses the variations in the physical parameters, such as temperature, pressure, displacement, and so on, and converts it to voltage or current. The control of industrial processes and automated manufacturing systems requests accurate, moreover, linearized sensor measurements, where numerous sensors have nonlinear characteristics. In mechatronic systems, accurate measurement of the dynamic variables plays a vital role for the actuators to function properly. This chapter presents linearization methods and a measurement system in mechatronics consisting of temperature sensors and the signal-conditioning circuits, providing detailed information on design process of an embedded measurement and linearization system. This system uses a 32-bit microcontroller for thermocouple (T/C) cold junction compensation, amplification of low output voltage, then conversion to digital, and linearization of the type K thermocouple's output by software to output a desired signal. Piecewise and polynomial methods are used in linearization software, and the implemented embedded system for the linearization of a type K T/C is presented as a case study. The obtained results are compared to give an insight to the researchers who work on measurement systems in mechatronics.

Innovative Control Techniques for Mechatronic Systems
An increasing number of robot-based application require the use of manipulators with small weight and limited inertia. Unfortunately these devices are also prone to undesirable vibration effects, which are due to the flexibility of their links. In order to reduce the unwanted vibrations in mechanisms retaining their high-speed motion particular control techniques must be employed [1, 2].

Challenges in the development of mechatronic systems: The mechatronic component
… and Factory Automation, 2008. ETFA 2008. …, 2008
There is a need to replace existing mechanical and electromechanical systems with new ones, where functionality will be mainly implemented by software. The traditional approaches in the development of this kind of systems, which are known as Mechatronic systems (MTSs), prove wholly inappropriate for today's problems that are characterized by complexity, dynamics and uncertainty. In this paper, challenges in the development of MTSs are discussed and the Mechatronic Component is proposed as the key construct to address these challenges. The means that the construct of mechatronic component addresses the challenges of synergistic integration, size and complexity and reuse are discussed and the infrastructure for a prototype implementation is described.
Challenges in Designing Mechatronic Systems
Journal of Mechanical Design, 2012
Development of mechatronic products is traditionally carried out by several design experts from different design domains. Performing development of mechatronic products is thus greatly challenging. In order to tackle this, the critical challenges in mechatronics have to be well understood and well supported through applicable methods and tools. This paper aims at identifying the major challenges, by conducting a systematic and thorough survey of the most relevant research work in mechatronic design. Solutions proposed in literature are assessed and illustrated through a case study in order to investigate if the challenges can be handled appropriately by the methods, tools, and mindsets suggested by the mechatronic community. Using a real-world mechatronics case, the paper identifies the areas where further research is required, by showing a clear connection between the actual problems faced during the design task and the nature of the solutions currently available. From the results obtained from this research, one can conclude that although various attempts have been developed to support conceptual design of mechatronics, these attempts are still not sufficient to help in assessing the consequences of selecting between alternative conceptual solutions across multiple domains. We believe that a common language is essential in developing mechatronics, and should be evaluated based on: its capability to represent the desired views effectively, its potential to be understood by engineers from the various domains, and its effect on the efficiency of the development process. to 132.207.4.76.

The case study in Sec. 5 is utilized to present real-world mechatronic design scenarios, and to argue about how well they are supported through current solutions. The paper concludes by a discussion in Sec. 6 and a conclusion in Sec. 7.
