MAIN PROBLEMS OF STEAM HEATER THERMAL PROCESS CONTROL

Yadryshnikov Oleg Dmitrievich

The problems faced by designers of control systems for a heat engineering object such as a steam heater are discussed in this article. The peculiarity of this class of objects is the change of its parameters during operation and the presence of a delay, which makes it difficult to choose a regulator and ensure the required quality of the system. The paper proposes a plan for the formation of knowledge about the object, which includes splitting the set of parameters of the object into groups in order to further synthesize the regulator for each specific group. Two possible variants of such splitting of parameters are distinguished: the simplest and analytical. Using the example of a steam heater, the parameters of which vary depending on temperature, the division into three main groups of parameters is shown and the corresponding object models are presented in the form of transfer functions of various orders.
