Abstract

Sustav za regulaciju temperature sastoji se od zračne komore, Peltierovog elementa, razvojnog sustava Stellaris EKS LM3S1968, pločice s H mostom te temperaturnog senzora. Peltierov element hladi ili grije ovisno o iznosu i smjeru struje koja se na njega dovodi. Kako bi se dobio promjenjivi napon na Peltierovom elementu razvijen je sklop u spoju H mosta upravljan mikrokontrolerom. Algoritam implementiran u mikrokontroleru određuje upravljačku veličinu za most na osnovu izmjerene i zadane referentne temperature. Nakon što je sustav identificiran, određene su prikladne vrste regulatora i proračunati njihovi parametri. Simulacijom na računalu te kasnijom provjerom na stvarnom sustavu uspoređeni su rezultati dobiveni razvijenim upravljačkim algoritmima.

Abstract (english)

The temperature control system consists of air chamber, Peltier element, evaluation board Stellaris EKS-LM3S1968, H bridge and a temperature sensor. Peltier element is cooling or heating depending on the strength and direction of supplied current. In order to obtain variable voltage on the Peltier element, a H bridge circuit was developed and controlled with a microcontroller. The algorithm implemented in the microcontroller determines the control signal for the bridge on basis of measured values and reference temperature. Once the system is identified, appropriate types of controllers were determined and their parameters were calculated. Results obtained with the developed control algorithms were compared by means of computer simulation and subsequent verification of the real system.
