Moving Horizon Estimation and Control of an Experimental Process
Motivation and related methods
Proposed approach : block diagram
Horizon based control and estimation
Controller formulation
Estimation formulation (Gatzke and Doyle, 1998)
Control implementation schematic
First case study: Four-tank system (Johansson and Nunes,1997)
Closed-loop process measurements, inputs, and residuals
Normalized disturbance estimates
Estimates for leak in tank 4
Estimates for leak in tank 2
Closed-loop comparison, pump 1 bias
Second case study: CO2 absorber / desorber process (Dore 1994)
Closed-loop simulation example
