Dynamic Signal Change Rate Limiter#

This block allows limiting the rate of change (derivative) of the input function and the value of the output function changes no faster than the rates of signal change, which are set through the input ports.

The derivative is determined by the formula (1):

(1)#\[ rate=\frac{u\left(t\right)-y\left(t-1\right)}{∆t} \]

Hint

When the derivative of the input function is within the specified speed limits: the output will be equal to the input one.

If the rate of signal change does not match the limits, the output signal will be determined by the formula {eq} RateLimiterDynamic2:

(2)#\[\begin{split} y\left(t\right)=∆t\cdot\ Min_{rate}+y\left(t-1\right)\\ y\left(t\right)=∆t\cdot\ Max_{rate}+y\left(t-1\right) \end{split}\]
