State Tracking of MRAC Systems in the Presence of Controller Temporary Failure Based on a Switching Method

State Tracking of MRAC Systems in the Presence of Controller Temporary Failure Based on a Switching Method

The state tracking problem for a class of model reference adaptive control (MRAC) systems in the presence of controller temporary failures is studied. Due to the controller temporary failure, the considered system is viewed as an error switched system. The properties of Lyapunov function candidates...
