modelLessEq
Less or equal (<=)
Extends from Interfaces.RealComparison (Partial interface for Real comparisons).
Information
Description
Model of comparison for Real numbers.
The output y is true if the inputs u1 is less or equal than u2.
Depending on the value of the sampling time (Ts), the model has two different behaviours:
Ts > 0
it behaves as a discrete time system,Ts <= 0
it behaves as a continous time system. No delay is introduced and events are generated when the output changes (this mode reduces the simulation time)
Parameters
| Type | Name | Default | Description |
|---|---|---|---|
| Real | Ts (from RealComparison) | 0.1 | sampling time |
| Real | eps (from RealComparison) | Modelica.Constants.eps*100 | tolerance for the comparison |
Connectors
| Type | Name | Default | Description |
|---|---|---|---|
| Modelica.Blocks.Interfaces.RealInput | u1 (from RealComparison) | input | |
| Modelica.Blocks.Interfaces.RealInput | u2 (from RealComparison) | input | |
| Modelica.Blocks.Interfaces.BooleanOutput | y (from RealComparison) | output |
