A reduced structure controller for a Grinder Circuit system

Abstract: In this paper a reduced structure multivariable controller is developed for the model of a closed-system grinding circuit. The said controller is developed using a novel technique which employs basis pursuit regularization in order to generate a family of solutions which together span the entire range from decentralized to centralized controllers. Using this information, and the performance-cost trade off which is also computed, the designer is then able to choose the required amount of controller complexity which can achieve the desired closed-loop performance levels.
