Adaptive Disturbance Suppression Output Regulation for Switched Systems With Multi-Source Disturbances

This article is concerned with the adaptive disturbance suppression output regulation (ADSOR) problem for the switched systems (SSs) subjected to multisource disturbances. The disturbances are consisted of the measurable unmodeled disturbance and unmeasurable dynamic neural network (DNN) modeling disturbance. First, an adaptive disturbance estimator (ADE) is designed to capture the unmeasurable disturbance. Then, via the ADE, the ADSOR controller, and the switching index are co-constructed to make the regulation on the system output and the suppression on the multisource disturbances of SSs. Further, for the SSs with multisource disturbances, the criteria are derived to force the OR performance as well as the multisource disturbance resistance performance, even though the subsystems are not individually capable of achieving these performances. Finally, the turbofan model simulation verifies the applicability and validity of the developed results.
