摘要：

To adaptively reduce the influence of phase lag of traditional current mode switching power amplifiers on system stability and static and dynamic performances for magnetic bearing systems, this paper proposes a new, simple, and effective phase-lead compensation strategy based on unsymmetrical current sampling resistance network. The common problems associated with the existing phase-lead compensation methods for magnetic bearing power amplifiers are successfully handled via this method without additional hardware or software resources. The effectiveness and superiority of this proposed strategy have been demonstrated by both simulation and experimental results.
