Infrared sensor-based temperature control for domestic induction cooktops 2014 Access copy available to the general public Unrestricted In this paper, a precise real-time temperature control system based on infrared (IR) thermometry for domestic induction cooking is presented. The temperature in the vessel constitutes the control variable of the closed-loop power control system implemented in a commercial induction cooker. A proportional-integral controller is applied to establish the output power level in order to reach the target temperature. An optical system and a signal conditioning circuit have been implemented. For the signal processing a microprocessor with 12-bit ADC and a sampling rate of 1 Ksps has been used. The analysis of the contributions to the infrared radiation permits the definition of a procedure to estimate the temperature of the vessel with a maximum temperature error of 5 °C in the range between 60 and 250 °C for a known cookware emissivity. A simple and necessary calibration procedure with a black-body sample is presented. info:eu-repo/grantAgreement/ES/DGA/Photonics Technologies Group-GTF info:eu-repo/grantAgreement/ES/MINECO/IPT2011-1158-920000 info:eu-repo/semantics/openAccess by http://creativecommons.org/licenses/by/3.0/es/ 2.245 2014 INSTRUMENTS & INSTRUMENTATION 10 / 56 = 0.179 2014 Q1 T1 CHEMISTRY, ANALYTICAL 31 / 74 = 0.419 2014 Q2 T2 ELECTROCHEMISTRY 14 / 27 = 0.519 2014 Q3 T2 info:eu-repo/semantics/article info:eu-repo/semantics/publishedVersion (orcid)0000-0003-0775-4641 Alonso, R.
