Limit the rate of change of a signal.

Nonlinear
Description
The Rate Limiter block limits the first derivative of the signal passing through it. The output changes no faster than the specified limit. The derivative is calculated using this equation:
u(i) and t(i) are the current block input and time, and y(i-1) and t(i-1) are the output and time at the previous step. The output is determined by comparing rate to the Rising slew rate and Falling slew rate parameters:
Data Type Support
A Rate Limiter block accepts and outputs signals of type double.
Parameters and Dialog Box
- Rising slew rate
- The limit of the derivative of an increasing input signal.
- Falling slew rate
- The limit of the derivative of a decreasing input signal.
