This paper proposes a development method to control thermoelectric by using customization proportional controller. Moreover, the system applied heat disturbance observer to estimation value heat disturbance outside object into the system. In the equipment part, Peltier device is selected to be the thermoelectric module device. This device is a type suitable for analysis thermal system, because the device has a fast respond and good stability, it is comparison with the device in this group. Also this proposal used high speed controller (FPGA) for the programming to control system. Moreover, about the circuit driver current and sensor temperature used digital system. It protected noise working well and easy to program with FPGA. The result of this research can be guideline for analysis to control thermal systems or to control temperature for various applications.
