Abstract
The conditions under which an adaptive control system can exhibit chaotic behavior are investigated and classified. Indirect adaptive control strategies are used for control of linear discrete-time plants, exclusively. It is shown that the strange behavior in adaptive control could arise due to unmodeled dynamics (or disturbances), a bad combination of parameter estimation and/or control law, and lack of persistency of excitation. A first-order system, subjected to various identification algorithms and control laws, is analyzed for illustrative purposes
