基于凸包顶点表示的汽车发动机模型标定边界建模
Boundary modeling in model-based calibration for automotive engines via the vertex representation of the convex hulls
摘要：
当在边界建模过程中使用凸包方法时，基于模型的校准（MBC）软件套件--例如MathWorks的基于模型的校准工具--可能需要大量计算，具体取决于建模的数据量。其原因是使用了凸包的半空间表示。我们在这里讨论另一种表示的凸包，顶点表示，证明能够减少计算成本。本文中的数值比较是在MATLAB中使用MBC命令执行的，并表明在某些条件下，顶点表示优于半空间表示。
英文摘要：
When using the convex hull approach in the boundary modeling process, Model-Based Calibration (MBC) software suites -- such as Model-Based Calibration Toolbox from MathWorks -- can be computationally intensive depending on the amount of data modeled. The reason for this is that the half-space representation of the convex hull is used. We discuss here another representation of the convex hull, the vertex representation, which proves capable to reduce the computational cost. Numerical comparisons in this article are executed in MATLAB by using MBC Toolbox commands, and show that for certain conditions, the vertex representation outperforms the half-space representation.
