ABSTRACT:
An advanced control block that implements multiple-input/multiple-output control, such as model predictive control, within a process control system uses a compensation block or algorithm and a single control model based on a single process model to provide advanced control in a process having widely variable process delay. The compensation block changes the execution period of the advanced control block to account for changes in the one or more process variables responsible for the variable process delay, which eliminates the need to provide different advanced control models or control definitions for different operating regions for a process in the cases in which the delay in a process output is correlated to a measurable process or control variable.
