1. Monitoring of the controller amplitude
Definition
The amplitude monitor evaluates the amplitude of the lambda control output.
The control oscillation recognition is robust and relatively simple; however, it can only recognize a large time delay, which leads to high oscillations of
the lambda control.
In order to recognise highly oscillating control, the control value of the lambda control must mutually reach or exceed either the lower and upper limit or
the applicable lower and upper thresholds for an applicable time.
