Damping Compensation for Active Vibration Isolation System With Active Disturbance Rejection Control

IET Electric Power Applications, Volume 20, Issue 1, January/December 2026.
The analysis of classic active disturbance rejection control (ADRC) for active vibration isolation systems (AVIS) with electromagnetic actuators demonstrates that directly applying ADRC to these systems has some shortcomings. To overcome the limitations of classic ADRC in AVIS with electromagnetic actuators, damping compensation is proposed to enhance ...
