A low-complexity state feedback fault-tolerant control scheme guaranteeing prescribed tracking performance is proposed for a family of uncertain nonlinear systems with unknown directions. Contrary to the current state-of-the-art, novel error transformation functions and new update laws related are introduced design such that no compensators or approximation structures needed, in spite actuation faults, component nonlinearities. The method verified via simulation on an inverted pendulum.
