Abstract

This paper proposes a dual rate output-feedback control approach for sampled-data MIMO systems with non-linear uncertainties. Design and analysis of L1 adaptive controller is extended to sampled-data systems framework. The controller is designed for detection of zero-dynamics attacks and uncertainty compensation. A sufficient condition on the sampling time of the digital controller is obtained that ensures stability of the closed-loop system. It is shown that the proposed controller can recover the performance of a continuous-Time reference system. A simulation study of an automatic voltage regulator is provided to validate the theoretical finding.
