Abstract
Active balancing systems, which can suppress vibrations induced by unbalanced machinery during the operation of modern rotating machines, have attracted considerable interest. A key part of an active balancing system is the active balancer. To improve the smoothness of the motion of active balancers, we present an adaptive proportional-integral (API) control strategy for rotor active balancing systems during acceleration. The developed control strategy is based on a newly designed Lyapunov function and the positive realness property of the transfer function. The proposed API control strategy provides additional damping for the fast convergence and smooth motion of the actuators. Several rotor systems are used as examples to investigate the performance of the proposed control strategy. The simulation results show that actuators achieve smooth motion using the new method.
