Estimate DC gain with step signal — Inject step signal into plant
on (default) | off
When this option is selected, the experiment includes an estimation of the plant DC gain.
The block performs this estimation by injecting a step signal into the plant.
CautionIf your plant has a single integrator, clear this option. For plants with multiple
integrators or unstable poles, do not use the Open-Loop PID Autotuner block.
Tunable: Yes

Block Parameter: EstimateDCGain
Type: character vector
Values: 'off' | 'on'
Default: 'on'
Step Amplitude — Amplitude of step perturbation
1 (default) | scalar
If Estimate DC gain with step signal is selected, the block estimates the DC gain by
injecting a step signal into the plant. Use this parameter to set the amplitude of the
signal. The considerations for choosing a step amplitude are the same as the
considerations for specifying Sine Amplitudes.
To provide the step amplitude via an input port, select Use external source.
Tunable: Yes
