Model output following control for an aluminum plate cooling process with a Peltier device

In this paper, model output following control based on command generator tracker is considered to realize the control for an aluminum plate cooling process with a Peltier device. The aluminum plate cooling process with a Peltier device is divided into two parts, that is, one part has the Peltier device and another part has not. The models of the two parts are established respectively, where the heat conduction between the two parts is considered as an inertia delay element in this paper. In order to achieve the satisfactory tracking performance for the process with the delay, the method of model output following control based on command generator tracker is presented in this paper. It is not necessary that the order of the reference model is the same as the actual system. However, instead of the order requirement, the plant must be almost strictly positive real, where the robust parallel compensator is designed to transform the augmented plant into almost strictly positive real. The effectiveness of the proposed methods is demonstrated by the simulation.
