Optimal control structure selection based on economics for continuous cross-flow grain dryer

Abstract: In this work, we present the control structure selection problem based on steady-state economics applied to a continuous cross-flow grain dryer model. The optimal selection of the controlled and manipulated variables and their set-points can be obtained for various external disturbance s...
