Effect of RHP zeros and poles on the sensitivity functions in multivariable systems

摘要

This paper examines the implications of Right Half Plane (RHP) zeros and poles on performance of multivariable feedback systems. The results quantify the fundamental limitations imposed by RHP-zeros and poles in terms of lower bounds on the peaks in the weighted sensitivity and complementary sensitivity functions.
