Abstract
A two-step procedure for solving problems of robust control of dynamic plants with uncertainties is proposed. Plant dynamics is first subjected to robust correction by means of a high-gain control loop in accordance with a given reference model. Since the corrected plant model is now known, standard control methods are then used. This approach is implemented in a two-loop control system: the inner loop provides robust correction of a plant, and the outer loop is responsible for the achievement of the control objective.
