摘要：AbstractWe analyze and exemplify how some classical control structures can be used for optimizing a chemical process directly. Some key structures in this context are split-range control and mid-ranging control. In applications, split-range control is primarily used to manage several manipulated variables (valves) affecting the same controlled variable, without explicit reference to a control objective, or optimization criterion. However, the same basic principle can be used for directly optimizing a process, or subprocess. In some cases that scheme provides a simpler and more clear cut solution than MPC. A similar observation applies to mid-ranging control (also known as input resetting control, or valve position control).
