Abstract

The synthesis of an optimal digital controller for a stochastic plant is considered. To optimize the control system, an integral quality criterion is proposed with minimization of the variance of the controlled parameter. The quality criterion takes into account the control influence on the technological process, which allows to minimize the consumption of material and / or energy resources in the management of industrial units. Using the methods of optimization theory for a single-loop control system, the structure and parameters of the digital controller are determined. The structure of the digital controller is analyzed from the parameters of the quality criterion and of the mathematical description plant. An example of the digital controller synthesis a for an automatic control system for the air temperature at the output of the CV-P°2L°N-63B/F-N ceiling conditioner, which showed the efficiency of the digital controller when compensating for random disturbances, is given. The obtained results are recommended to specialists on automation for control system design and optimization of the existing.
