modelNominalLifeRating
Calculation of nominal life rating for linear roller guides
Extends from Modelica.Blocks.Interfaces.SI2SO (2 Single Input / 1 Single Output continuous control block).
Information
This blocks computes output y as sum of the two input signals u1 and u2:
y = k1*u1 + k2*u2;
Example:
parameter: k1= +2, k2= -3
results in the following equations:
y = 2 * u1 - 3 * u2
