Multi-description coding-decoding-based control for interval type 2 T-S fuzzy systems with mixed time-delays

This paper discusses a control problem for a class of interval type-2 T-S fuzzy systems with mixed time delays. A multi-description coding and decoding mechanism is utilized to improve the reliability of data transmission. The measurement output is separately coded into two descriptions with rank and file information, and then the coded two descriptions are transmitted to the decoder via two independent communication channels which are random occurring packet dropouts. Sufficient conditions are established to assess the exponentially input-to-state stable in mean-square sense, and an explicit relationship is proposed for the effect of packet dropouts on decoding accuracy. Furthermore, the controller gains are calculated by applying the orthogonal decomposition technique. Finally, the applicability and effectiveness of the control method is illustrated by numerical simulation results. (c) 2023 The Franklin Institute. Published by Elsevier Inc. All rights reserved.
