Industrial Automatic Control Systems and Controllers Annotation << Back Greenhouse Temperature Control System V.I. Domanov, A.V. Domanov, E.V. Pevcheva The analysis and synthesis of the greenhouse temperature control system was carried out. The features of the control object – large inertia and change in parameters during operation – are noted. To improve the accuracy and stability of accuracy and stability of maintaining a given temperature value, it is proposed to use invariant chains and proactive correction. With this in mind, the structural scheme of the system under study was synthesized. The formulas and recommendations for setting up the system are given. To increase the efficiency of the invariant chain, it is necessary to use the inertia of the control object. The use of proactive correction changes the transmission coefficient of the system. To restore it, it is proposed to switch on the compensating circuit. The setting for the required mode of operation, taking into account the changing parameters, is made on the basis of the determination of the vibrational index. According to the obtained results, 3D-graphics were built, allowing to select the parameters of the proactive correction. A system simulation was carried out and graphs were constructed confirming the effectiveness of the decisions made.
