Abstract
In this paper, a scheme based on Elliptical Transformation is proposed for phase-stabilization of resonant modes at above Nyquist frequency. With the proposed scheme, disturbance is suppressed without large spillover effects at an aliased resonant mode at 12 kHz and an out-of-phase resonant mode which is in close proximity at 14 kHz.
