ROBUST DECENTRALIZED CONTROL OF REACTIVE DISTILLATION PROCESS IN DIMETHYLACETAMIDE PRODUCTION

Abstract The paper deals with the sequential synthesis procedure of decentralized (multi-loop) PID-controllers based on the estimation of control loops interaction in the form of multiplicative plant uncertainty. It is shown that the each synthesis iteration is accompanied by the correction of the robust performance criteria for the coupled SISO-systems. The results of industrial application of proposed sequential design for reactive distillation unit is cited as well as comparison analysis with the other techniques is given.
