A feedforward approach to mid-ranging control
(2021) In Control Engineering Practice 108(March). p.1-10- Abstract
Mid-ranging control is a control strategy that is used when there are more than one manipulated variable available to control a process variable. Mid-ranging control handles the redundancy by coordinating the roles of the different manipulated variables. The most common approach is to introduce valve position controllers (VPC) that control the relations between the manipulated variables. In this paper, some drawbacks of the VPC approach are pointed out, and a new control strategy that overcomes these drawbacks is presented. Instead of using valve position controllers, the new strategy uses feedforward control to coordinate the manipulated variables. Design methods for both the new strategy and the VPC controller are presented in the... (More)
