Adaptive control method ensures tracking accuracy in nonlinear systems with constraints, indicating effective management of input challenges.
This work addresses a challenging adaptive tracking issue for uncertain nonlinear systems, featuring a nontriangular structure, full state constraints, and dead‐zone input. A new constrained adaptive control approach is presented by exploring the adding one power integration and fuzzy control. With the selection of a suitable barrier Lyapunov function, we design an adaptive controller, which guarantees the desired tracking accuracy and the boundedness of all system signals. Besides, the system states do not violate the constraint. The proposed method is verified using numerical and practical examples.
