Rate Limiter
The limiting rate of change of the signal.
blockType: RateLimiter
|
Path in the library: |
Description
Block Rate Limiter limits the first derivative of the signal passing through it. The output does not change faster than the specified limit. The derivative is calculated using the usage of this equation:
Where
-
and — input data of the current block and time;
-
and — Output data and time in the previous step.
The output signal is determined by comparing with parameters Rising slew rate and Falling slew rate:
-
If more parameter Rising slew rate ( ), the output signal is calculated as
-
If less than a parameter Falling slew rate ( ), the output signal is calculated as
-
If located between borders and , a change in the output is equal to a change in the input:
