Self-optimizing control - A survey
Self-optimizing control is a strategy for selecting controlled variables. It is distinguished by the fact that an economic objective function is adopted as a selection criterion. The aim is to systematically select the controlled variables such that by controlling them at constant setpoints, the impact of uncertain and varying disturbances on the economic optimality is minimized. If a selection...

Perry Y. Li Roberto Horowitz Department of Mechanical Engineering Department of Mechanical Engineering University of Minnesota University of California at Berkeley 111 Church St. SE Berkeley CA 94720-1740 Minneapolis MN 55455 [email protected] [email protected] Abstract Self-optimizing control problems arise in applications where the desired task is implicitly speci ed as an optimization of...
متن کاملSelf-optimizing Control: a Distillation Case Study
The following important question is frequently overlooked: Which variables should we control? The answer is related to finding a simple and robust way of implementing the optimal operating strategy. It is argued that the controlled variables should be those that that give “self-optimizing control”, which is when acceptable operation is achieved with constant setpoints for the controlled variabl...
متن کاملOptimal Operation of a DWC by Self-Optimizing Control: Active Vapor Split Approach
Dividing Wall Column(DWC) offers the large potential for operating and capital cost saving in compared with conventional distillation sequence. In the studied DWC in this study, the aid of Vmin diagrams, it is shown that without a suitable value for vapor split fraction bellow the dividing wall in different operating conditions, the energy requirement increases from optimal value and it wil...
متن کاملOptimal Operation of a Three-Product Dividing-Wall Column with Self-Optimizing Control Structure Design
This paper deals with optimal operation of a three-product Dividing-Wall Column (DWC). The main idea is to design a control structure, through a systematic procedure for plantwide control, with an objective to achieve desired product purities with the minimum use of energy. Exact local method is used to find the best controlled variables as single measurement or combination of measurements ...
