Mechatronic system

High temperature compatibility - a large proportion of the key applications in high volume markets are found in automotive or industrial control systems with high temperature requirements (e.g. engine management, mechatronics systems, etc.).

Actuators can be classified as conventional and unconventional actuators. Conventional actuators are commonly used as essential components for mechatronic systems (see Pig. 1 (left)). These are, for instance, electrical motors, pneumatic actuators, hydraulic pistons, or relays.

Various subsystems interact within a mechatronic device in a complex manner as shown in Fig. 2 (Isermann 2003 de Silva 2005 Necsulescu 2009). The individual components of the mechatronic system are therefore often highly integrated with regard to function and space. The block diagram below is also known in control engineering as the basic stmcture of a closed loop system.

On a more concrete level, development engineers can employ computer-aided simulation systems in order to model, analyze, and optimize the behavior of a mechatronic system. Especially the dynamic interactions of the system components are in the focus of the simulation...

The visualization of function dependabilities of mechatronical system in an appropriate way can be used for mapping the relations to matrix-oriented relations. Determination of system architecture and reliability analysis for system composed of simple hardware with known fault histories or elaborately discussed in many literatures. But when a system is based on software or more complex hardware components, describing of the system architecture, and its reliability will be challenging. However, in such cases, determination of system architecture at a reasonable level seems to be inevitable during design phase. Once the system architecture is available in an appropriate mathematical form, reliability evaluation of the system is possible. After finishing this step the considered modules can be defined as atomic blocks/units. By means of the defined blocks it is possible to describe the whole system functionality in a suitable reliability-oriented manner. 

Mechatronic system reliability evaluation using petri networks and PHI2 method... 

Only one aspect of the methodology is dealt with in this paper, namely the way in which time variant mechanical reliability for a mechanical component can be integrated into the functional and dysfunctional modeling of a complex (notably mechatronic) system achieved using Petri Nets. The first part describes how the Petri Nets are applied. The second part reexamines the principle of time variant mechanical reliability, and more specifically the PHI2 outcrossing rate that enables analysis of time variant failure... 

Functional and dysfunctional modeling makes it possible to assess the performance of the various structures of a mechatronic system in order to identify the one that best meets requirements. The presence of a... 

In this paper, we have presented an approach that enables us to assess time variant failure probability using the PH 12 method, which we propose integrating into the Petri Nets rehahihly analysis of a mechatronic system. The physical model of the system under consideration (a mechatronic system) allows us to obtain the functional times of the various system components. These times are used in the functional transitions of...

However, implementation of cold-standby strategies is more sophisticated because of the meeting the requirements to detect failures as they occur and activate the redundant component. This is not necessary for active redundancy because all components will be never idle. In addition to its complex implementation due to diagnostic inspection and cost of such system, deploying of standby redundancy have been a poor choice in the vehicle context so far. However deploying active redundancy is very popular, a system design is required synchronistically implement active and stand-by redundancy in various parts of new mechatronic system in order to achieve certain level of reliability.

All the synthesis steps mentioned above can be executed either automatically or interactively. The programmed ASIC emulator can be inserted directly into the overall mechatronic system to facilitate real-time test runs. In the following, all main synthesis steps will be described in the same top-down sequence as they are implemented through the synthesis script. Throughout the rest of the chapter, the terms ASIC emulator (board), rapid prototyping board, and target architecture will be used synonymously. 

The application domain and ASIC emulator architecture strongly influence the overall synthesis script as well as the actual algorithms for solving single synthesis tasks. In order to achieve efficient solutions, our whole approach has been tuned toward real-time system applications as they are found in mechatronic systems. To support the understanding of the implemented approach/algorithms, this section will describe the intended application domain and ASIC emulator architecture in more detail. 

This synthesis approach is tuned toward real-time applications appearing in mechatronic systems, such as an adaptive shock absorber, a combustion engine controller, intelligent tire friction control, volume stream measurement, etc. A large number of microelectronic subcomponent designs have been studied [8]. As a result, it was found that the designs typically share the following common characteristics ...
