Abstract
En 中文
• Delay-dependent eigenvalue trajectories are tracked without repeated eigensolutions.
• Device and control parameters, constant delays, and stochastic WAMS delays are varied.
• Sparse DDAE structure is preserved for large-scale stability analysis.
• Real-world-scale tests show speedups over QZ and Krylov–Schur.
