This thesis addresses the system-level modeling and simulation of MEMS devices using the analog extensions of the hardware description language, SystemC. We first evaluate the capabilities of models of computation proposed by the SystemC-AMS standard implementation. We then demonstrate the limitations of equivalent models to properly describe the geometry and internal couplings of MEMS devices. To enrich the simulation, we propose to integrate reduced models exported from the finite-element analysis tool MEMS+ directly in SystemC-AMS. To this end, we implement a C++ Application Programmable Interface (API) as well as a module library. Our solution enables to insert lightweight models representing MEMS in usual SystemC-AMS test benches. After reviewing the main API features, we finally test our solution with an accelerometer model and compare the simulation results to state-of-the-art solutions, focusing on accuracy and performance. This thesis introduces a novel system-level framework to efficiently test MEMS models within their surrounding electronics in a unified simulation environment.
Mechanical complex systems, such as helicopters, require more and more detailed design while an increasing number of modeling and simulation tools is available. Model Driven Engineering, first applied in computer science, proposes methods based on meta-modeling concept enabling the collaboration and federation of software. These techniques are considered in this study as a way to enhance complex systems control design based on multiphysics description. The study focuses on bond graphs (BG) and energetic macroscopic representation (EMR) which are commonly used to detail energetic exchanges into systems. The present work describes both a BG and EMR metamodel, as well as model transformation that can be used to generate a EMR model from a BG model. The implementation is realised under Eclipse Modeling Framework (EMF). The transformation is validated and analyzed through its application on an industrial usecase : the design of a helicopter flight control subsystem.
