Revisit Nyquist-Bode Stability Criteria for Power Electronic System with Non-minimum Phase System

After a long period of development, stability criteria are gradually improved. Among them, Nyquist-Bode stability criterion plays an important role. However, traditional Nyquist stability criterion is only applicable to minimum phase system. With the development and wide application of power electronic technology, minimum phase system is just a small portion of all the power electronic systems. To analyze the stability of non-minimum phase system, a more general Nyquist-Bode stability criterion is essentially needed.
