Abstract

Journal of Vibration and Control, Ahead of Print.
For time-varying constraints in nonlinear systems with unmeasured states, a finite-time fuzzy tracking control strategy is constructed. A state observer based on fuzzy logic systems (FLS) is applied to not only approximate the unknown nonlinear functions, ...
