Jalkio Analytical vs. Numerical Models Partial vs. Ordinary Differential Equations Stochastic vs. Deterministic University of St. Thomas Models Linear vs. Nonlinear If mechatronics design is more than just the combination of electronic software and mechanical design the additional feature must lie in the ability of the mechatronic designer to optimize a design solution across these disparate fields. This requires a sufficient understanding of each of these fields to determine which portions of an engineering problem are best solved in each of these domains given the current state of technology. In turn this requires the ability to model the problem and potential solutions using techniques that are domain independent or at least permit easy comparison of solutions and tools from different domains. For example the optical inspection system shown in Fig. 22.1 depends on optical components in precise alignment mechanical elements capable of precise motion transducers for sensing and providing mechanical power electrical systems to control motion and filter sensor signals and software for image analysis and motion control. Only by dividing these tasks appropriately among electronics mechanical components and software can the system be optimized. This requires an understanding of all the system requirements and limitations as well as the capabilities of each component in the various domains. Modeling of requirements and systems is crucial in determining whether a proposed solution is acceptable as well as in documenting these determinations for future use. In this article we shall examine the varieties of models used at different points in the design process the diverse roles
