Abstract

This investigation analytically and experimentally explores the structure-wide vibration suppression performance of an input/output based, multi-harmonic adaptive vibration control (MHAVC) on a magnetic bearing controlled, flexible driveline system. Here, effects of imbalance, misalignment and load-torque are considered. Based on analysis developed for linear-periodic time-varying plants, this research finds that robust structure-wide vibration suppression can be achieved by moderating the MHAVC least-squares solution. It is found that this can be accomplished through design of a control effort penalty weighting or by utilizing non-collocated auxiliary sensor information. Here, robustness with respect to driveline operating conditions (speed, torque, misalignment and imbalance) is achieved.
