Finite-Time Stability and Controller Design of Continuous-Time Polynomial Fuzzy Systems

Abstract EN

Finite-time stability and stabilization problem is first investigated for continuous-time polynomial fuzzy systems.

The concept of finite-time stability and stabilization is given for polynomial fuzzy systems based on the idea of classical references.

A sum-of-squares- (SOS-) based approach is used to obtain the finite-time stability and stabilization conditions, which include some classical results as special cases.

The proposed conditions can be solved with the help of powerful Matlab toolbox SOSTOOLS and a semidefinite-program (SDP) solver.

Finally, two numerical examples and one practical example are employed to illustrate the validity and effectiveness of the provided conditions.
