robust control principles, conditions of uncertainty, robust regulatorAbstract
The class of non-stationary, multidimensional and multiply connected facilities, in particular, three-column distillation-rectification unit (DRU) of indirect action, which is characterized by complex hydrodynamic, mass- and heat exchange processes, is considered in the paper. For effective control of the class of facilities, a robust approach was selected, since the purpose of robust control synthesis is ensuring the required system quality, regardless of possible errors and changes in system parameters.
The main objective of robust control is guaranteed control in conditions of incomplete priori information about the object, ensuring the system stability and maintaining its quality in the presence of all types of uncertainties which are studied and clearly identified for the DRU.
The aim of the study is the use of robust approach for optimal control of the selected class of facilities to guarantee quality and stability of automated control system in cases of emergency situations of technological regime.
