The research deals with control methods of multifactorial objects of food production, representing diverse technological processes occurring in continuous, discrete-continuous and discrete modes. This is especially relevant for systems in food production having the series connection of technological units, separated by apparatus-technological capacities and resistances. For such units, a transient delay value is significantly greater than that of single-capacity objects. A solution proposed: the use of two-loop automatic control systems capable of improving system quality parameters in facilities of chemical and technological processes. The two-loop automatic control system is relevant when the object is subjected to frequent disturbing influences from the regulator and has a low inertia parameter. The internal control loop suppresses arising internal disturbance caused by the specifics of the process itself, and the external loop is responsive to disturbing influences coming from outside, e.g., with changing properties of the incoming raw materials.
