Abstract :
Sufficient conditions for adaptive control to ensure stability and convergence to a controller that is robustly stabilizing and performing are developed, provided that such a controller exists in the candidate controller pool. The results can be used to interpret any cost-minimizing adaptive scheme. An example of how a recently developed adaptive switching method can fail to select a stabilizing controller is presented, and a correction is proposed.
