This study suggests a method to derive an approximate but sufficient formula of an open-loop transfer function for examining the oscillation seen for power devices connected in parallel. The stability ...

Add your perspective 4 How to handle complex systems? When faced with complex open-loop transfer functions or multiple feedback loops, drawing or interpreting a root locus plot can be difficult.

The proposed approach is robust with respect to multi-model uncertainty closed-loop sensitivity functions in the Nyquist diagram through the constraints on their infinity norm. The H∞ constraints are ...
