Nonlinear sensorless cooling control for a Peltier actuated aluminum plate thermal system

In this paper, a modeling and a coprime factorization presentation of a nonlinear aluminum plate thermal system with a Peltier device are investigated. A new operator based sensorless control system of the process is proposed. The effects of uncertainties and unknown coupling effects of the process are compensated in the proposed design method. The effectiveness of the proposed system is shown by experimental results.
