Fuzzy Adaptive Prescribed Performance Control for a Class of Uncertain Nonlinear Systems with Unknown Dead-Zone Inputs

Abstract EN

This paper proposes a fuzzy adaptive prescribed performance control scheme for a class of uncertain chaotic systems with unknown control gains and unknown dead-zone inputs.

Firstly, an error transformation is introduced to transform the original constrained system into an equivalent unconstrained one.

Then, based on the error transformation technique and the predefined performance technique, a fuzzy adaptive feedback control method is developed.

It is shown that all the signals of the resulting closed-loop system are bounded.

Finally, an illustrative example is given to demonstrate the effectiveness and usefulness of the proposed technique.
