System-level model of electrothermal microsystem with temperature control circuit

Abstract

In this paper we demonstrate a system-level simulation of a temperature controlled microsystem which is based on a reduced order model of a micro hotplate. Together with the electro-thermal microstructure we have implemented a control scheme, which allows the hotplate to operate either at a defined setpoint independent of ambient temperature or to follow defined temperature sweeps. An optimization algorithm was employed to identify suitable parameters for a PI-controller.
