Smart Electric Drives for Mechanical System Identification and Active Vibration Control

Participating speaker: Omer Ikram ul Haq, ABB.

Abstract: Mechanical resonances and vibrations can limit the operating range, reliability, and performance of electric drivetrains. This seminar presents how a variable frequency drive can go beyond conventional motor control and become an active tool for mechanical system identification and vibration mitigation. Controlled torque excitation can be used to identify resonance characteristics and mechanical parameters, while vibration feedback enables active damping by applying counteracting torque pulsations. During the seminar, we will also show how ABB Crealizer™ enables these algorithms to be developed and tested in simulation using real ACS880 control firmware before deployment to the actual drive, creating a practical path from modeling and identification to real-time vibration control.
