Multidisciplinary Integrated Simulation and Design Optimization Framework for Electromechanical Servo System

Abstract

This paper presents a tailored multidisciplinary integrated simulation and design optimization framework for electromechanical servo system (MISDOF-EMSS). The work intends to develop flexible integrated simulation techniques and efficient MDO methods to design advanced electromechanical servo systems in modern industries in a more effective and efficient manner. The proposed framework was developed based on ModelCenter commercial MDO framework because of its opening architecture for process integration and algorithm extension. The hardware and software configurations of MISDOF-EMSS were introduced at first in terms of the application requirements. Parametric geometry modeling toolkit was developed based on Pro-E, which provides the unique geometry source to link various disciplinary simulations. All the disciplinary analysis models were implemented in batch mode using automation techniques, and then seamlessly integrated in MISDOF-EMSS by using ModelCenter’s Filewrapper protocol. Advanced MDO methods including optimization algorithms, surrogate modeling techniques, MDO strategies are implemented in MISDOF-EMSS using Plug-in interface, VB script and Marco in ModelCenter. Finally, an application case of permanent magnet synchronous motor (PMSM) optimization was performed to verify the practicability and applicability of the proposed MISDOF-EMSS.
