Stabilization of Filament Production Rate for Screw Extrusion-Based Polymer 3D-Printing
Shumon Koga, David Straub, Mamadou Diagne +1
Polymer 3D-printing has been commercialized rapidly during recent years, however, there remains a matter of improving the manufacturing speed. Screw extrusion has a strong potentia…
Sampled-Data Control of the Stefan System
Shumon Koga, Iasson Karafyllis, Miroslav Krstic
This paper presents results for the sampled-data boundary feedback control to the Stefan problem. The Stefan problem represents a liquid-solid phase change phenomenon which describ…
Single-Boundary Control of the Two-Phase Stefan System
Shumon Koga, Miroslav Krstic
This paper presents the control design of the two-phase Stefan problem. The two-phase Stefan problem is a representative model of liquid-solid phase transition by describing the ti…
Extremum Seeking for Traffic Congestion Control with a Downstream Bottleneck
Huan Yu, Shumon Koga, Tiago Roux Oliveira +1
This paper develops boundary control for freeway traffic with a downstream bottleneck. Traffic on a freeway segment with capacity drop at outlet of the segment is a common phenomen…
Input-to-State Stability for the Control of Stefan Problem with Respect to Heat Loss
Shumon Koga, Iasson Karafyllis, Miroslav Krstic
This paper develops an input-to-state stability (ISS) analysis of the Stefan problem with respect to an unknown heat loss. The Stefan problem represents a liquid-solid phase change…
Arctic Sea Ice State Estimation From Thermodynamic PDE Model
Shumon Koga, Miroslav Krstic
Recent rapid loss of the Arctic sea ice motivates the study of the Arctic sea ice thickness. Global climate model that describes the ice's thickness evolution requires an accurate…
Delay Compensated Control of the Stefan Problem and Robustness to Delay Mismatch
Shumon Koga, Delphine Bresch-Pietri, Miroslav Krstic
This paper presents a control design for the one-phase Stefan problem under actuator delay via a backstepping method. The Stefan problem represents a liquid-solid phase change phen…
