Quantized Feedback Control Design of Nonlinear Large-Scale Systems via Decentralized Adaptive Integral Sliding Mode Control

Abstract EN

A novel decentralized adaptive integral sliding modecontrol law is proposed for a class of nonlinear uncertainlarge-scale systems subject to quantization mismatch betweenquantizer sensitivity parameters.

Firstly, by applying linear matrixinequality techniques, integral-type sliding surface functions arederived for ensuring the stability of the whole sliding modedynamics and obtaining the prescribed bounded L 2 gainperformance.

Secondly, the decentralized adaptive sliding modecontrol law is developed to ensure the reachability of the slidingmanifolds in the presence of quantization mismatch, interconnectedmodel uncertainties, and external disturbances.

Finally, an exampleis shown to verify the validity of theoretical results.
