PROBLEM TO BE SOLVED: To provide an adaptive process controller which determines a set of continuously scheduled process model parameters which are used to develop controller tuning parameters for controller tuning.SOLUTION: A state-based, adaptive PID controller uses a new technique to determine an appropriate process model to be used to perform adaptive tuning over various operating regions of a plant, and in particular, uses a process model parameter determination technique that enables continuously scheduled process model parameter update over the various plant operating regions or points. The use of this continuously scheduled process model parameter update method provides for smoother transitions between the tuning parameters used in the PID controller during adaptive tuning procedures which are implemented based on changes in the operating region or the operating point of the process, thereby providing for better overall control. |
