Abstract:
The evolution of what is called small mechatronic system took a more and more important dimension for these last ten years. Nowadays, the number of actuators, sensors increases fast in a lot of fields. The development of these future systems requires a sustained research of high level to allow a miniaturization of these elements for one thing and an increased autonomy by means of "smart" electronics on the other hand. Energy saving is also a key issue for our future which is also strongly dependent of devices efficiency, even for small power consumption. Connections with material science and information technology are the key for innovation in this topic. Existing technologies must be used in an unconventional use to create innovation. The proposed keynote intends to show some examples of multidisciplinary projects and show how to combine some exiting technologies in a smart way. The link with industries will be highlighted as a common thread in all breakthrough innovations. Electro-active polymer actuator for blood pump as well as magnetorheological fluid of diabetic shoese design will be highlighted during this presentation.

Abstract:
Depending on the type of machine and the type of analysis, state-of-the-art software and powerful computers may be indispensable. Reduction of the calculation time, without or with little loss of accuracy, has always been and will always be pursued. So-called model-order reduction (MOR) is one means for effecting this. In practice, broadly speaking, MOR can mean very different things, from mathematical black-box or grey-box approaches involving matrix-level operations, down to simple engineering and physics-based pragmatism. This will be illustrated by looking at permanent-magnet synchronous machines (PMSMs) and focusing on eddy-current effects and how to consider these with state-of-the-art methods.
