Abstract: An IGBT physical model parameter extraction method includes obtaining an initial value and a transformation range of an IGBT physical model parameter; and correcting a model parameter by means of a correspondence between IGBT dynamic and static features and the IGBT physical model parameter and in combination with an experiment measurement result of the IGBT physical model parameter.

Abstract: Provided are a monitoring device, a method for setting reference baseline and a readable storage medium. Whether the monitoring device has a system error is determined due to at least one event, according to at least one of the moving state of the target object, the connection state of the target object and the signal acquisition device, the environmental information where the target object is located, and the analysis result of the monitoring device. When the monitoring device has a system error, the current reference baseline of the monitoring device is updated according to the preset rules, and then the monitoring is continued based on the new reference baseline. In this way, the current reference baseline of the monitoring device can be adjusted in time, false alarms and missed alarms caused by the system error can be avoided and the accuracy of the monitoring device can be improved.
