Method for modeling and or simulation of non-linear system elements does not require solving of non-linear equation systems and so has reduced calculation times, e.g. for calculation of pressures and flows in a hydraulic system

摘要

Method has the following steps: Actual operating states for an initial given time and operating point are measured; the non-linear curves of the system elements are linearized using the tangent to the operating point; the values required for an actual operating point are calculated using a linear equation system; and finally iterative integration is used for dynamic system elements to find new known states for the next defined time point. The invention also relates to a corresponding program product for implementation of the inventive method.
