By definition, mechatronic systems involve coupled structural and control properties. Therefore, optimization of mechatronic systems requires an integral optimization of both. In this paper, we study the optimal design of a simplified motion control system. In particular, we develop a methodology which utilizes topology and shape optimization to create a parameterized structure and improve its dynamic characteristics. The obtained structure is used as a starting point for combined structural and control optimization. We compare performances of the systems optimized by sequential and nested optimization approaches. The nested optimization procedure results in a better final performance.
Keywords: topology optimization, nested optimization, combined structural and control optimization, proportional-integral-derivative (PID) controller.
