A new software to show the behaviour of the PID controller. Part II. Influence of the setting parameters of DSCs

Some DSC calorimeters, such as the model DSC 111, built by the society Seta ram, allow the user to set the temperature programming parameters. Usually default values furnished by the constructor are often used, but it is very interesting to study the thermal behaviour of the regulation of the calorim eter under different conditions and with different kinds of set point tempe ratures. For this research, we have developed in C language a set of software in ord er to demonstrate the behaviour of the (proportional integral derivative) P ID controller of the DSC. It can help the user to choose correct values for P, I and D parameters according to the kind of experiment conducted. The s oftware allows studies of extra parameters, such as the sampling rate of th e computerized PID controller or the determination of filtering of the corr ection.
