Abstract
In traditional methodologies for mechatronic design, the design processes of the mechanical structure, the electromechanical actuators and the control system, is more or less independent of each other. The mechanical structure is usually designed first, then fitted with off-the-shelf electric motors and drive electronics, and finally, a controller is designed for the already existing physical system. This approach leads to that many of the possible advantages of mechatronic design solutions not are exploited. It is necessary to increase the integration between the design processes of the different domains to reach a better result from the mechatronic design process. Only then, is it possible to find the optimal system design, not just the sub-optimal design resulting from each engineering domain. The mechatronics revolution in the automotive industry, with its large production volumes, opens up for the development of highly integrated mechatronic modules, designed to actuate a specific load, such as a power steering actuator. This in turn calls for new, integrated, cross-domain design and optimisation methods for mechatronics. Integrated design of electric motors, gears, power electronics and controller enables optimisation of the whole mechatronic system, not just each domain separately. This paper presents an approach to integrated design of all constituent components in mechatronic actuation modules, which has the potential of reducing the systemâ„¢s weight, size, energy consumption and cos
