Robust Optimization of an Accelerometer Considering Fabrication Errors

Abstract: A robust optimization approach of an accelerometer is presented to minimize the effect of variations from micro fabrication. The sensitivity analysis technology is employed to reduce design space and to find the key parameters that have greatest influence on the accelerometer. And then, the constraint conditions and objective functions for robust optimization and the corresponding mathematical model are presented. The optimization problem is solved by the Multiple-island Genetic Algorithm and the results show … Show more

“…Liu, Jiang, and Wang (2009) performed a robust optimization considering both bandwidth and sensitivity of a similar device, and Desrochers, Pasini, and Angeles (2010) first optimized the shape of the hinges used in their bulk design and then performed a multiobjective size optimization aiming to maximize the sensitivity and minimize the ratio between the first and the second natural frequencies to reduce off-axis sensitivity. Mukherjee, Zhou, and Fedder (1999), Coultate et al (2008) and Engesser et al (2010) presented analytical models for a surface-micromachined accelerometer, by proposing optimized designs considering different requirements.…”

“…In an engineering optimal design problem, design variables will have uncertainties from manufacturing clearance, uneven material properties, etc [1,2]. These uncertainties in design variables often move the nominal optimal design to the infeasible region so that it will violate some constraints as shown in Fig.…”
