Abstract

In this paper, a novel Multivariable Adaptive Super-Twisting Algorithm is proposed. Considering a multilayered structure, the proposed adaptive scheme does not require the knowledge of upper bounds for the matched disturbances and their derivatives. Extracting information from the equivalent control, a second-order sliding mode is achieved by adapting both gains in a non-conservative way, potentially reducing the undesirable effects of chattering.
