The paper contributes to the understanding of the behavior of adaptive control systems in anomaly situations. In particular it explores phenomena which are due to interaction between disturbances and unmodeled dynamics. It is shown that the persistency of excitation plays a major role. Ways to ensure that difficulties do not occur are also presented.
