Robust tuning of industrial regulators based on standard (step-response)
identification techniques
A standard technique for the tuning of industrial regulators is based
on the analysis of the step response of the plant. However,
additional analysis of the step response allows to extract information
useful to deduce a frequency-domain bound on the model errors.
P.Rocco is studying this problem, with the aim of finding
simple tuning rules for PID regulators based on robust control
concepts. Some results have already been found on the
correlations between some error indexes associated to the step
response and the corresponding error bound.
