Cascaded process model based control: Packed absorption column application
Nonlinear, adaptive, process-model based control is demonstrated in a cascaded single-input–single-output mode for pressure drop control in a pilot-scale packed absorption column. The process is shown to be nonlinear. Control is demonstrated in both servo and regulatory modes, for no wind-up in a co...

| description | Nonlinear, adaptive, process-model based control is demonstrated in a cascaded single-input–single-output mode for pressure drop control in a pilot-scale packed absorption column. The process is shown to be nonlinear. Control is demonstrated in both servo and regulatory modes, for no wind-up in a constrained situation, and for bumpless transfer. Model adaptation is demonstrated and shown to provide process insight. The application procedure is revealed as a design guide to aid others in implementing process-model based control.
•Cascaded process-model based control is demonstrated on a pilot-scale unit with nonlinear behaviors.•The controller is tested in servo, regulatory, mode transfer, and constrained situations.•Model adaptation is shown to provide useful information about the process. |
