✦ Synopsis

This paper presents an indirect model reference adaptive control for minimum phase linear systems of arbitrary order with unknown high frequency gain sign. It is proved that the (modified) estimate of the high frequency gain has a uniform positive lower bound. The problem has been solved by using the least squares covariance matrix properties to define an appropriate modification of the parameters estimates. *

## Abstract This work presents an indirect, model reference adaptive control for minimum phase linear systems of arbitrary relative degree. Global stability of the closed‐loop system is proved in spite of bounded disturbances and asympotic tracking is achieved in the ideal case.

Recently, a design of model matching and adaptive control systems under the presence of measurement noise employing a nonminimal order state observer was reported. But this method cannot be used for the case where the plant has deterministic disturbances. In this paper, we will show that the idea is
