  • Abstract
    Studies the quadratic stability analysis problem for linear time-invariant multi-input multi-output systems which have time-varying positive real or sector-bounded uncertainty feedback. The author proves that the positivity theorem and circle theorem are necessary and sufficient conditions for quadratic stability, for positive real and sector-bounded feedback, respectively
