Abstract

This note gives an upper limit on the adaptation rate of an adaptive control algorithm when there exists model order mismatch. Under the condition that an operator H2 is strictly positive real (SPR), the adaptive control algorithm is stable for a sufficient small estimation rate epsilon. An upper limit for epsilon is explicitly given.
