SummaryThis article addresses an adaptive fuzzy practical fixed‐time tracking control for nonlinear systems with unknown actuator constraints and uncertainty functions. First, fuzzy logic systems (FLSs) are used to identify uncertain functions. Then, by utilizing FLSs, backstepping technique, and finite‐time stability theory, an adaptive fuzzy practical fixed‐time control is proposed to obtain satisfactory tracking performance even when the actuator faults. The theoretical analysis verified that the closed‐loop systems is practical fixed‐time stable under the proposed control strategy, the tracking error converges to a small neighborhood of the origin in a fixed time, and the convergence time is independent of the state conditions. Finally, both numerical simulation and physical example demonstrates the effectiveness of the proposed control strategy.
