Limit rising and falling rates of signal
The Rate Limiter Dynamic block limits the rising and falling rates of the signal.
The external signal up sets the upper limit on the rising rate of the signal.
The external signal lo sets the lower limit on the falling rate of the signal.
Follow these guidelines when using the Rate Limiter Dynamic block:
Ensure that the data types of up and lo are the same as the data type of the input signal u.
When the lower limit uses a signed type and the input signal uses an unsigned type, the output signal keeps increasing regardless of the input and the limits.
Use a fixed-step solver to simulate models that contain this block.
Because the Rate Limiter Dynamic block does not support continuous sample time, simulation with a variable-step solver causes an error.
The Rate Limiter Dynamic block accepts input signals of the following data types:
The data type of the output signal Y matches the data type of the input signal u.
