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