Impedance Model Based Stability Control
The instability of the drive system is caused by the interaction of the LC resonance and the constant power load (CPL), hence the active damping methods have been applied to damp the resonance and stabilize the drive system.

Preface
Reduced DC-link capacitance motor drive system has been developed for its higher reliability, higher power density, lower cost, and longer lifetime. Compared with the conventional drive system equipped with large volume electrolytic capacitors, the DC-link capacitance is reduced remarkably. The DC-link voltage fluctuates obviously, and the coupling between the grid input side and the inverter output side is enhanced. Many techniques have been developed to improve the drive system performance in the last few decades. The book focuses on the advanced control of reduced dc-link capacitance AC motor drives. The proposed control strategies are verified by experimental results, which include high power factor control, drive system stability control, beat phenomenon suppression, enhanced flux-weakening control, anti-overvoltage control, etc. The major features of this book are the systematic analysis
