Randomized trial evaluates energy-based methods for damping identification and settling in vibrating systems, suggesting reliable outcomes.
Key Points
This research aims to develop and validate energy-based methods for identifying the damping ratio in linear vibrating systems, both underdamped and overdamped.
Proposed energy-based schemes for damping ratio identification in underdamped and overdamped systems.
Numerical validations were performed against logarithmic decrement and half power bandwidth methods.
Introduced energy-based settling criteria that are insensitive to initial conditions.
Energy-based damping identification for underdamped systems showed errors below 1%.
Overdamped damping identification provided results with errors under 2%.
Proposed settling criteria correlated well with standard 2% settling-time criteria, maintaining consistency.
