Abstract [en]

Mechatronic systems design is a challenge. In order to best use the synergetic effects of such systems, they need to be designed in an integrated manner. Therefore, holistic mechatronic systems design requires considering both multiple domains and multiple optimization targets concurrently. Previous research by the authors presents a novel approach to mechatronic systems design by enabling swift optimization and subsequent evaluation of mechatronic design concepts. The optimization method builds upon algebraic models relating component performance to e.g. size and weight, and linear transfer function models which are used to capture dynamic properties. The swiftness of the method comes from the fact that the holistic optimization is performed without simulation. This paper extends the design methodology by integrating polynomial control design into the holistic optimization procedure as a front-loaded activity, as to reduce time and cost consuming design iterations in later design phases. In order to consider constraints regarding a quick optimization and evaluation, the control design is carried out in the frequency domain. The control performance, i.e. how well a particular mechatronic concept handles the exogenous signals (command, disturbance, noise) is considered as specification rather than optimization criterion. The novelty is found in the application of a polynomial control approach in context of holistic design optimization and evaluation.
