Adaptive Output-feedback prescribed performance control (PPC) scheme is investigated for a class of uncertain switched nonlinear systems. Compared with the existing methods; this paper designs a new type of error transformation function. Its advantage is that based solely on the properties of the function; the output error can be constrained within the preset band without any additional conditions. Neural networks are used to approach unknown nonlinearities in switched systems; and state observers are used to estimate unknown states. The stability analysis shows that the proposed method ensures that all closed-loop signals are bounded and the tracking error can converge to the adjustable constraint function under the switching condition of average dwell time. Finally; the effectiveness of the proposed algorithm is verified by simulation experiments. © 2024; International Association of Engineers. All rights reserved;
