Abstract
In this paper, we describe a thennal control of a thermoelectric cooler / heater with Peltier device which is operated by the Peltier Effect. Generally, it is said that the thermal control with Peltier device is difficult because of its nonlineariry. In order to deal with the nonlinearity, we use nonlinear model predictive control for the thermal control of the device. A nonlinear model of the thermal system with Peltier device is derived. The validity of the model is evaluated by experimental results. Nonlinear model predictive control system is designed for the model. Recursive Kalman filter is used to estimate the unobservable state variables. The experimental results show the accurate control performance. The robustness against themal load is also verified by the experiments.
