Information
This information is part of the Modelica Standard Library maintained by the Modelica Association.
The SlewRateLimiter block limits the slew rate of its input signal in the range of [Falling, Rising].
To ensure this for arbitrary inputs and in order to produce a differential output, the input is numerically differentiated
with derivative time constant Td. Smaller time constant Td means nearer ideal derivative.
Note: The user has to choose the derivative time constant according to the nature of the input signal.
Parameters (6)
| Rising |
Value: 1 Type: Real Description: Maximum rising slew rate [+small..+inf) [1/s] |
|---|---|
| Falling |
Value: -Rising Type: Real Description: Maximum falling slew rate (-inf..-small] [1/s] |
| Td |
