The Rate Limit block limits the rate of change of a signal. The rate of change is calculated by

where, u is the input signal, y is the output signal,
is the current simulation time
step,
is the previous
simulation time step. If rate is between the Rising rate parameter
and the Falling rate parameter, the output signal is equal to the input
signal.
If rate is greater than the Rising rate parameter, the output signal is calculated by

where, R is the Rising rate parameter.
If rate is less than the Falling rate parameter, the output signal is calculated by

where, F is the Falling rate parameter.
