Driveline SciML Demo

A two-stage parameter calibration of a nonlinear torsional isolator in an EV driveline. The plant combines three torque paths — a quasi-static baseline, a Maxwell relaxation element, and a Bouc-Wen hysteresis element — and the demo recovers the hidden isolator parameters from designed excitations: a low-amplitude frequency sweep followed by slow full-amplitude cycling, via SciML optimization.

Note

This is a heavy SciML demo. The model diagram below renders from a snapshot, but the calibration runs are not executed in the documentation build. Run them from the DrivelineSciML project.

The model

DrivelineSystem is the assembled two-inertia EV driveline: the torque source, engine inertia, Maxwell-Bouc-Wen isolator, load inertia, load damper, and ground:
