A note on the control of processes exhibiting input multiplicity
Robert J. Lovelett, Yorgos M. Psarellis, Ioannis G. Kevrekidis +1
Steady state multiplicity can occur in nonlinear systems, and this presents challenges to feedback control. Input multiplicity arises when the same steady state output values can b…
Partial observations and conservation laws: Grey-box modeling in biotechnology and optogenetics
Robert J. Lovelett, Jose L Avalos, Ioannis G. Kevrekidis
Developing accurate dynamical system models from physical insight or data can be impeded when only partial observations of the system state are available. Here, we combine conserva…
Some manifold learning considerations towards explicit model predictive control
Robert J. Lovelett, Felix Dietrich, Seungjoon Lee +1
Model predictive control (MPC) is a de facto standard control algorithm across the process industries. There remain, however, applications where MPC is impractical because an optim…
A stochastic model of solid state thin film deposition: application to chalcopyrite growth
Robert J. Lovelett, Xueqi Pang, Tyler M. Roberts +3
Developing high fidelity quantitative models of solid state reaction systems can be challenging, especially in deposition systems where, in addition to the multiple competing proce…
