Impedance-Based Temperature Estimation in Induction Hardening Using a UKF with FEM-Trained Hybrid Surrogate Models
This paper presents a method for estimating the internal temperature field of a cylindrical workpiece during an induction hardening process using an Unscented Kalman Filter (UKF). Since the internal temperature distribution cannot be measured online, the estimator infers this field by exploiting its direct physical eff...
