Abstract

The electrical conductivity of metal-oxide gas sensors depends on the gas atmosphere and on the temperature of the sensor. In order to eliminate this influence, temperature control systems for gassensors were developed as conventional PID-controller. Problems appears in cases of hard disturbances (i.e. rough gasflows) to fix a temperature point what is justified with the high non linearity of the controlled system. A new concept based on fuzzy logic was developed to gain better temperature stabilization in atmospheres with hard disturbances. This control system was adapted in the laboratory and tested in a real sensor application. The fuzzy system can optimize the system for different disturbances.
