Rate Limiter
Purpose
Limit rising and falling rate of change
Library
Control / Discontinuous
Description
The Rate Limiter restricts the first derivative of the signal passing through it. While the rate of change is within the specified limits, the output follows the input. When the rate of change exceeds the rising or falling limit, the output falls behind the input with a fixed slope until output and input become equal again.
Parameters
- Rising rate limit
The maximum rate of change of the output signal (typically positive).
- Falling rate limit
The minimum rate of change of the output signal (typically negative).
- Sample time mode
This parameter lets you choose whether the block operates with a continuous sample time, or whether the sample time is inherited from the input. The default is
continuous. See also Sample Times.
Probe Signals
- Input
The input signal.
- Output
The output signal.
