%X A hierarchical control approach for industrial process operation is proposed to achieve the desired technical indices (TIs) by using the extended multivariable decoupling control technique. The lower-level loop control system designed by the multi-loop PI/PID control technique is responsible for forcing the key process variables that closely relate to the TIs to track the given setpoints. By using the extended decoupling control method within a unity feedback structure, we develop a higher-level setting controller for the generalized plant consisting of the controlled process and the lower-level control system. To achieve the desired TIs, this setting controller automatically adjusts the setpoints for the lower-level controllers in response to process uncertainties and disturbances with good decoupling performance. An application to the grinding process is presented to demonstrate the proposed control approach.
