数据表的多变量函数计算往往构成了与动力系统仿真相关联的整个计算要求的一个主要部分。本文讨论了一种使用脱机计算制定在联机实时计算期间执行速度更快的修正数据表的新方法。文中有两个实际例子:六自由度的导弹仿真程序和六自由度的飞行仿真程序,都用来说明这种新方法。在这种新方法中,运行程序的时间分别减少19％和11％。 Multivariate function calculations for datasheets often form a major part of the overall computational requirements associated with powertrain simulation. This article discusses a new way to use offline calculations to formulate faster data tables for correction during online real-time calculations. There are two practical examples in this paper: six degrees of freedom missile simulation program and six degrees of freedom flight simulation program are used to illustrate this new method. In this new approach, the time it took to run the program was reduced by 19% and 11%, respectively.
