  • <p>The reliable stabilization of elongated plasmas is a prerequisite for the success of magnetic confinement fusion. Vertical Displacement Events (VDEs) in highbeta spherical tokamaks, such as NSTX-U, present a</p> <p>formidable control challenge due to high growth rates</p> <p>(γ ≈ 500 rad/s) and significant sensor noise. This paper presents the latest iteration of the AION-CORE</p> <p>architecture, a deterministic, dual-layer control kernel designed for sub-microsecond response. The core</p> <p>innovations in v19.2 include the replacement of the</p> <p>Alpha-Beta filter with an Adaptive Kalman Filter</p> <p>(AKF) for optimal state estimation, and the integration of a **Realistic Physics Model** incorporating</p> <p>effective plasma mass, wall damping, and **RL Actuator Dynamics**. We demonstrate, through highfidelity simulation, that this hybrid approach successfully maintains the plasma within acceptable limits,</p> <p>showcasing the SMC Guardian’s robustness against a</p> <p>complex, non-ideal plant. The architecture is optimized for FPGA implementation, ensuring deterministic, low-latency operation essential for future fusion</p>
