Multifidelity Data Fusion Based on Gradient-Enhanced Surrogate Modeling Method
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: A multifidelity surrogate (MFS) model is a data fusion method for the enhanced prediction of less intensively sampled primary variables of interest (i.e., high-fidelity (HF) samples) with the assistance of intensively ...
An Integrated Surrogate Modeling Method for Fusing Noisy and Noise-Free Data
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: Many datasets in engineering applications are heterogeneous mixtures of noise-free data, noisy data with known noise variances, and noisy data with unknown noise variances. This article proposes a data fusion method called ...
Model-Free H∞ Output Feedback Control of Road Sensing in Vehicle Active Suspension Based on Reinforcement Learning
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: An active suspension system ensures the controllability of a vehicle in the vertical direction, which greatly enhances the control redundancy and safety of an intelligent driven vehicle. However, many calibrated model ...
An Adaptive Two-Stage Kriging-Based Infilling Strategy for Efficient Multi-Objective Global Optimization
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: Most practical multi-objective optimization problems are often characterized by two or more expensive and conflicting objectives, which require time-consuming simulations. Commonly used algorithms construct a surrogate ...
A Method to Resolve Simulation of Discontinuous Flow Field: A Valve Example From Full Closing to Re-Closure
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: In transient computational fluid dynamics (CFD) simulations, the continuity of the flow field is an essential prerequisite. However, continuous flows can be separated under certain conditions, such as the process from valve ...
A Sequential Sampling Generation Method for Multi-Fidelity Model Based on Voronoi Region and Sample Density
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: Multi-fidelity surrogate model-based engineering optimization has received much attention because it alleviates the computational burdens of expensive simulations or experiments. However, due to the nonlinearity of practical ...
