Specify Input Offset and Step Amplitude Level for Step Response

This example uses:

Control System Toolbox Control System Toolbox

Open Live Script

Create a transfer function model.

sys = tf(1,[1,1]);

Create an option set for step to specify input offset and step amplitude level.

opt = stepDataOptions('InputOffset',-1,'StepAmplitude',2);

Calculate the step response using the specified options.

[y,t] = step(sys,opt);

Input Arguments

Name-Value Arguments

Specify optional pairs of arguments as Name1=Value1,...,NameN=ValueN, where Name is the argument name and Value is the corresponding value. Name-value arguments must appear after other arguments, but the order of the pairs does not matter.

Before R2021a, use commas to separate each name and value, and enclose Name in quotes.

Example: ...,'InputOffset',2

`InputOffset` — Input signal offset level
0 (default) | scalar

Input signal offset level, specified as the comma-separated pair consisting of 'InputOffset' and a scalar, for all time t < 0, as shown in the following figure.

`StepAmplitude` — Change of input signal offset
1 (default) | scalar

Change of input signal offset level, specified as the comma-separated pair consisting of 'StepAmplitude' and a scalar, which occurs at time t = 0, as shown in the previous figure.
