The aim of the study was to investigate the applicability of DMC control algorithm to control the temperature of potatoes in the storage. Principle of regulating the temperature of stored potatoes using the above algorithm, and simulations were performed. The obtained results were compared with the effects of currently used in the storage of potatoes control algorithms: the two-position and the PID (proportional-integral-differential). Preliminary results of the temperature control system simulation of potatoes in storage, exercising control algorithm DMC indicated that this system compared with conventional control systems makes it possible to achieve the desired temperature of potatoes in less time, and also provides more accurate control without overshoot. Thus a better quality of regulation, lower technological losses and the required quality of stored potato tubers are ensured. Moreover, taking into account the weights in the objective function of optimizer allows such a process control that optimizes energy consumption.
