In this article, we pay our attention on exploring observer-based actuator fault and sensor fault reconstruction associated with fault-tolerant control (FTC) for nonlinear systems, which are approximated by the Takagi-Sugeno (T-S) fuzzy method. By designing a brand-new unknown input observer (UIO),...
