Using the example of the hydraulic system "hydrostatic transmission system" a soft sensor network is developed and researched to improve operational strategy. The detection of the system state will be realized by the synthesis of axiomatic and dimensional analytical model descriptions of the components with recorded measurement sizes. The targeted redundant determination of system sizes leads to data induced conflicts. The resolution of these conflicts either leads to greater confidence in the model-based specific sizes or register the detection of system changes. Using model adaptation the soft sensor network is able to respond to changes in the system behavior, for example by wear.

以液压系统“静液压传动系统”为例，研究开发了一种用于改进操作策略的软测量网络。系统状态的检测将通过合成具有记录的测量尺寸的部件的公理化和维度分析模型描述来实现。系统大小的有针对性的冗余确定导致数据引起的冲突。这些冲突的解决方案要么导致基于模型的特定尺寸的更大置信度，要么记录系统变化的检测。使用模型自适应，软传感器网络能够响应系统行为的变化，例如磨损。
