Modelling of a hyperfast switching Peltier cooling system using a variable time delay model

This paper describes the modeling of a hyperfast switching Peltier cooling system. Linear output-error models are applied to model the influence of input variables on the output of the system. From the frequency response analysis of the collected data, it is observed that there is an uncertain time delay in one of the channels. By adding a variable time delay term into the model, the error at the output can be significantly reduced in the validation set.
