Model Based Design and HIL Simulations

Computer-Aided Design and Applications

A new methodology for communicating engineering information called Model Based Denition is gaining popularity. In this article a comparison will be made of the socalled traditional way that engineers communicate their ideas using engineering drawings, where the drawing is the authority, and this new Model Based Denition methodology, where the 3D model is the authority. The pros and cons of implementing Model Based Denition are critically analysed. The conclusions drawn from this analysis indicate where further development is needed if Model Based Denition is to become more widely accepted.

Multidisciplinary engineering is essential to develop mechatronic products. The key factor is to integrate methodology, systems and models. This paper will discuss the various design representations and the dependencies between product models. An approach for capturing dependencies is presented.

Nowadays, model-based and knowledge-based system engineering bring completely new demands also to the master degree teaching process and programs. Specifically, it is necessary to establish gluing technologies between individual master degree courses while full STEM education scope is covered. Since huge changes in educational system are often subject to complex, time demanding evaluation and approval process, there is usually significant delay between actual industrial needs and time when universities are able to deliver to the market engineers with required knowledge and curricula. Consequently, solutions which can be implemented in actual courses without huge investments of money and time is what educators should strive for. This paper shows how simple hardware-in-the-loop (HIL) simulators may help during the whole training period while respecting needs of already established courses dealing e.g. with modeling and simulation, control design, industrial IT and communication, control HW and electronics, sensors and actuators. The concept is demonstrated on several examples of already proven procedures in primary and second control courses.

24th Digital Avionics Systems Conference, 2005

The term "Model based design and development" has grown in popularity over the past decade. Within the embedded avionics community the term model based design implies the development and application of "control models and simulations" within tools such as MATLAB. At Honeywell, the authors have been engaged in model based development (MBD) and associated tools development for avionics applications. This position paper applies the lessons learned and discusses several issues, relating to sound modelbased design, to meet design assurance and certification objectives. The paper examines the dominant approaches utilized by some of the popular model-based design, code generation and verification tool suites available commercially. It contrasts these approaches to traditional software design, implementation, and verification methods. This paper also recommends taking a broader perspective of MBD and suggests adopting lessons learned from the classical software engineering arena. We discuss this together with areas for future investigation, standardization, and automation tool development and integration

Seventh International Conference on Application of Concurrency to System Design (ACSD 2007), 2007

The software design is one of the most challenging tasks during the design of a mechatronic system. On one hand, it has to provide solutions to deal with concurrency and timeliness issues of the system. On the other hand, it has to glue different disciplines (such as software, control and mechanical) of the system as a whole. In this paper, we propose a model-driven approach to design the software part of a mechatronic system, which consists of two major parts: systematic modeling and correctness-preserving synthesis. The modeling stage is divided into four steps, which focus on different aspects (such as concurrency, multiple disciplines and timeliness) of the system respectively. In particular, we propose a set of handshake patterns to capture the concurrent aspect of the system. These patterns assist designers to build up an adequate top-level model efficiently. Furthermore, they separate the system into a set of concurrent components, each of which can be further refined independently. Subsequently, the multidisciplinary and realtime aspects of the system are naturally specified and analyzed in a series of refinements. After the important aspects of the system are specified and analyzed in a unified model, a software implementation is automatically synthesized from the model, the correctness of which is ensured by construction. The effectiveness of the proposed approach is illustrated by a complex production cell system.

The evaluation of the emergent behaviour in complex systems requires an analytical framework which allows the observation of different phenomena that take place at different levels. In order to observe the dynamics of complex systems, it is necessary to perform simulations so that both local and the emergent behaviour can be observed. To this end, the way in which complex system simulators are built must be examined so that it will be feasible to model large scale scenarios. In this paper, the use of Model Driven Engineering methodology is proposed to deal with this issue. Among other benefits, it is shown that this methodology allows the representation and simulation of a complex system providing support for the analysis. This analysis is supported by a metamodel which describes the system components that are under study. The application of this methodology to the development of large scale simulators is explored through a case study. This case study analyses a complex socio-technical system: a power grid.

The development of mechatronic systems involves the use of multiple disciplines, from mechanical engineering to electronics engineering and computer science. Traditionally, every discipline was developed independently and then integrated to generate the final system. However, high-quality designs cannot be achieved without simultaneously considering all the engineering disciplines. This integrated approach carries an intrinsic complexity into system design process and numerous researches are ongoing in order to find out optimal methods. This article illustrates a methodology based on Model-Based System Engineering to support the integrated development of complex mechatronic devices. The main contribution is the introduction of a design methodology based on the W model and the identification of SysML as the tool to support the whole process. This method will also address the problem of ''devices interchangeability'', that means the possibility to develop the functionality of a system with different operation principles, at a very early stage of the development process (i.e. during the conceptual development). To achieve this goal, the methodology treats the problem of linking the conceptual with executable models to enable the validation by simulation. Main advantages of this methodology are in providing, to the mechatronic systems designers, a fixed schedule which does not limit their intuition and reduces complexity through a hierarchical approach. The process has been tested through the rationalization of the choices that have brought to the current solution of the filling system of an automatic filling machine for liquid foodstuff.
