Mechatronic Systems: Modelling and Simulation with HDLs

This paper presents a new methodology for modeling and simulation of hybrid systems which is called Hybrid High-level Nets (HYNETS). The new methodology integrates three established modeling approaches into one language. High-level Petri Nets represent the basic discrete framework, differential algebraic equations (DAEs) are used to describe continuous systems behavior and object-oriented concepts improve the expressiveness and compactness of models. The paper explains basic ideas of the language and illustrates its usefulness with a small example.

Hybrid high-level nets

This work pursues a new approach for the modeling of micro mechanics in systems of the micro system technology: The modeling bases on a building block set of models for basic effects The model equations of the effects are based on analytic equations, which need little computing time and thus suitable for system simulations The models were implemented in an analog hardware description language (VHDL-AMS, IEEE standard 10761) This supports the co-simulation of electronics and mechanics, and thus the simulation of complete micro systems in circuit simulators 
For the automatic design of the layout of silicon-based micro mechanical structures a layout generator was created, which is based on a commercially available GDS-II library A synthesis tool with integrated user interface provides the necessary data for the coherent layout generation and model conception on basis of functional values This supports the design of micro-electromechanical systems (MEMS) with the top-down method The method is illustrated on the basis of micro mechanical demonstrators: a pressure sensor system, a gyroscope, an accelerometer and a micro mirror system

Kohärente Layoutsynthese und Modellbildung von skalierbaren mikroelektromechanischen Strukturen

In this paper, we present a new approach to embedded system design based on modeling discrete and also continuous system parts with high level Petri—Nets. Our investigations concentrate on a complete design flow, analysis on high level Petri—Nets and their meaning for hardware/software partitioning of real-time embedded systems. The concepts for hybrid modeling of discrete and continuous systems are applied in an example in the domain of mechatronic systems.

Towards a complete design method for embedded systems using predicate/transition-nets

This paper describes the hierarchical, graphical SEA Language. The SEA Language relies on extended Predicate Transition Nets that unambiguously define the semantics of graphical system specifications. These nets are also used as a basis for simulating/animating system specifications. The SEA Language allows to easily incorporate several user defined or standardized graphical symbols and their behaviour. Via this approach a unified semantic basis for different graphical specification formalisms/techniques can be provided. These techniques may be application independent like data flow graphs, statecharts or block diagrams for differential equations or application dependent like logical gates for hardware systems. Hence, engineers can specify system (parts) using the graphical symbols they are used to. Due to the underlying common semantics defined by extended Predicate Transition Nets, a heterogeneous system can be specified and simulated as a whole at very early stages of design before some system components are already constructed. This approach and its benefits will be explained using the well known elevator system as an example of a heterogeneous system.

The SEA Language for System Engineering and Animation

Current systems are no longer pure physical systems or information systems but tend to consist of elements from both of these areas Thus, one modelling technique which considers the behaviour of all the different system elements is elaborated within this paper Extended Predicate/Transition nets often used for information technology serve as a basis for this modelling It is shown how differential equations as used for the description of the physical elements can be modelled by this technique Linear and nonlinear systems are regarded as well as the coupling of these systems For continuous modelling of the equations a continuous Predicate/Transition net is presented
