Dynamical feedback control with operator learning for the Vlasov-Poisson system
Jingcheng Lu, Li Wang, Jeff Calder
To meet the demands of instantaneous control of instabilities over long time horizons in plasma fusion, we design a dynamic feedback control strategy for the Vlasov-Poisson system…
Controlling instability in the Vlasov-Poisson system through moment-based optimization
Jingcheng Lu, Li Wang, Jeff Calder
Controlling instability in plasma is one of the central challenges in fusion energy research. Among the various sources of instability, kinetic effects play a significant role. In…
Continuous data assimilation for hydrodynamics: consistent discretization and application to moment recovery
Jingcheng Lu, Kunlun Qi, Li Wang +1
Motivated by the challenge of moment recovery in hydrodynamic approximation in kinetic theory, we propose a data-driven approach for the hydrodynamic models. Inspired by continuous…
Revisting high-resolution schemes with van-Albada slope limiter
Jingcheng Lu, Eitan Tadmor
Slope limiters play an essential role in maintaining the non-oscillatory behavior of high-resolution methods for nonlinear conservation laws. The family of minmod limiters serves a…
