Acceleration of the Measurement Time of Thermopiles Using Sigma-Delta Control

Acceleration of the Measurement Time of Thermopiles Using Sigma-Delta Control

This work presents a double sliding mode control designed for accelerating the measurement of heat fluxes using thermopiles. The slow transient response generated in the thermopile, when it is placed in contact with the surface to be measured, is due to the changes in the temperature distributions t...
