Instability analysis and improvement of robustness of adaptive control. (English) Zbl 0548.93050
Five cases of instability under applying adaptive control in singularly perturbed systems are considered on examples. Then the authors propose a modification of a previously developed procedure, excluding the appearance of instability in more general situations.
