“…Thermal control/actuation by peltier devices has been investigated in a wide variety of studies [5]. For example in [6,7] the device was used to construct a virtual thermal resistance. But most investigations focus on effective control of the peltier cold-side, see e.g.…”

In this study a practically feasible Input-Output linearizing feedback law is introduced and tested on an experimental setup. The test setup is representative of part of a medical handheld diagnostics device, requiring fast and accurate temperature control in large temperature ranges. The setup is modelled with an in-house developed lumped mass modelling tool to allow for efficient controller design and synthesis. Furthermore, the setup is controlled via a National Instruments DAQ-unit that communicates with Matlab Simulink on a Windows-based computer. The building blocks in Simulink enabling this are also in-house developed. Experimental results show that the practically feasible control law is capable of dealing with large temperature variations in the setup as well as high frequent fluctuations in the setpoints.

For the purpose of cooling the electronic device rapidly, a cooling system based on Peltier elements has been designed and manufactured. The mathematic model of the system was built by theoretic deduce. The system is able to actively control the euthermic device's virtual thermal resistance to its surroundings and efficient cooling can be achieved.According to the proposed model, the relation between the input power of the Peltier cell and the power loaded on the euthermic device was simplified, moreover, a new multi-modal control strategy based on low power consumption was presented. The experiments proved that the use of this cooling system with our control strategy increased the control precision up to 0.8% when the power loaded on the euthermic device was at 12W.

“…1a and c, active control occurs when the TE couple works as a thermoelectric heat pump hence heat transfer through it is controlled by input voltage magnitude and polarity [31]. The variation of heat flow is achieved by changing the electric current supplied to the thermoelectric module so an external power source is required [32].…”
