A robust pole placement indirect adaptive control algorithm is analyzed. It is shown that a dead zone technique can be used so that it does not necessarily require any a priori knowledge on the bound of the unmodeled dynamics and bounded disturbances, and the resulting closed-loop adaptive control system is stable under some conditions. Tolerable unmodeled dynamics could be enlarged if the knowledge of the upper bound of the unmodeled dynamics is given.
