Distributed Proportional-Integral Control Law Capabilities for the Temperature Maintaining System within the Vertical Greenhouse

The report presents the results concerning the applicability of distributed control of temperature regime in vertical greenhouses. The distributed generalization of the proportional-integral control law is proposed. The capabilities of distributed control were estimated under various proposals on the distributed disturbances including random and nonstationary ones, the presence of “forbidden zones” for issuing control actions, as well as on the various forms of prescribed temperature distribution along with the greenhouse height. The results of simulation have shown good perspectives of distributed control application to maintain the individual temperature regimes at different height levels corresponding to the conditions of joint cultivation of different agricultures in a common greenhouse.
