A design method was proposed for the fixed-gain feedback controller which is sufficiently robust under the variations of process dynamics. The variations or uncertainties in the process dynamics are represented by variations of uncertain parameters in the process model. For each typical operational condition the region of possible variation is approximated by an orthotope. This orthotope is the required region of tolerance. On the other hand, the region of uncertain parameters, in which the control system has admissible system performance, is the inherent region of system tolerance. The controller is designed so that the inherent region of tolerance contains the required region of tolerance. The design algorithm is composed of the iteration of two steps: a robustness test for the proposed design and a controller parameter retuning for the required tolerance. The method was applied successfully to processes for which the dynamics depends on the throughput.
