5.42. STAB

Purpose

To transform an input signal . The transformation is done according to a table.

Procedure

Interpolation of the ‘function table’ is done if the input signal falls within the ‘function table’ limits. No extrapolation is done if the input signal falls outside the limits, instead the nearest value in the ‘function table’ is output.

Parameters

Parameter	input	unit	range	default	remarks
Function table	table

Remarks

Both columns in the ‘function table’ must be in SI-units.

Examples

Table 1 presents a STAB ‘function table’. Figure 1a presents the input signal (sine) generated by FUN component and figure 1b presents the output signals for the STAB component.

It can be seen that from 2 s to 10 s the input signal is above the ‘function table’ limits and a value of 5 is output. From 15 s to 23 s the input signal is outside the limits and a value of 2 is output. In the other time intervals the input signal is within limits and interpolation is used.
