The thermoluminescence dating is attracted the attention of geology or archaeology researchers as a new method. This method needs a heating device to raise the temperature of the sample continuously atexact rate. This paper describes a design method of the a control system to accomplish the purpose. This control system tends to beunstable because of the existence of parameter perturbation and lag time. In this paper the perturbation and the lag time are treated as perturbations of a generalized system regarded as a one-order system.Tracking characteristic in the low frequency domain and robust stability in the high frequency domain of the control system is achieved using the mixed sensitivity problem which is a kind of H^∞ control theories.Experiments verify the effectiveness of this method.
