SYNTHESIS OF AUTOMATIC CONTROL SYSTEM BY TECHNOLOGICAL PROCESS OF CARBON DIOXIDE PREPARATION IN THE PROCESS OF UREA PRODUCTION

The article deals with the development of multivariable automatic control system of mount for carbon dioxide preparation in the process of urea production. The product quality and cost price depend on its quality. The results of using linear quadratic regulator as a basis of digital system of automatic control of the mount are described. The multivariable multilinked model including the peculiarities of dynamics of all devices of processing system is used for synthesis.
