modelLookup_Table
Table-based lookup with manual input of the interpolation table
Extends from Interfaces.PartialCLD.Lookup (Partial lookup for causal loop diagramming).
Information
This information is part of the Business Simulation Library (BSL). Please support this work and ► donate.
Using the lookup converter →TableFunction the normalized current value of the stock, which is connected via the StockInfoInput connector, is used as input to an interpolation table (manual input) to obtain the output y.
The value used for the normalization is a constant by default (referenceValue = 1); if hasConstantReference = false the optional input u is used instead.
Notes
- The reference value for normalization should be strictly positive; the divison for normalization is protected against divison by zero and will return zero in that case.
- Instead of using the current value of a connected stock, the input connector u can be used as basis by setting
hasStockInfoInput = false.
