Identify(ref UnitDataSet, bool, bool)

Identifies a PID-controller from a UnitDataSet

Declaration

public PidParameters Identify(ref UnitDataSet dataSet, bool downsampleOversampledData = true, bool ignoreFlatLines = true)

Parameters

Type	Name	Description
UnitDataSet	dataSet	a UnitDataSet, where .Y_meas, .Y_setpoint and .U are analyzed
bool	downsampleOversampledData	Boolean, whether to do internal oversample identification and attempt downsampling. Defaults to true.
bool	ignoreFlatLines	Boolean, whether to do internal flatline identification and ignore their indices. Defaults to true.

Returns

Type	Description
PidParameters	the identified parameters of the PID-controller
