This method is used to control technological facilities, such as heating furnaces, chemical reactors, steam cauldrons, etc. It enhances accuracy and swiftness while reducing the expenditures in the saving agent : fuel or materials. The method helps to determine whether each transition process is prompted by a change in the assignment, or is due to disturbances, while the managing impact consists of two components. One of them is formed following the proportional-integral law and has an uninterrupted action, while the other comes on impulse. The impulses are with maximum permissible value with the respective polarity, while their duration is different for the two types of transition processes, depending on the starting conditions and the dynamics of the facility, and is proportionate to the relative expenditure of the main agent, the mistake and the first derivative of the leading value. The ratio coefficients are selected so that the transition processes are critically periodic.
