Observer design for interconnected systems with model reduction and unknown inputs

摘要

In this paper a combination of distributed parameter systems and lumped parameter systems is investigated, also known as interconnected system. In particular, the heat distribution and the influence of single chips on a base plate is of interest, here in context of insulated-gate bipolar transistors. Only temperature measurements on the base plate are available. A method is presented with which the temperature inside the chip can be estimated. A combination of model reduction and unknown input observer is utilized.
