“…Compared with the existing works, the superior advantages of this work contribute to the following aspects. - This article formulates a noncooperative game for high‐order nonlinear systems, and thereby the considered problem can cover the existing works associated with first‐order systems, 16‐19 second‐order systems, 22,23 and multiintegrator systems 24 as special cases. Moreover, the focused players are subject to input saturation, input delay and external disturbances, which renders the existing seeking algorithms not applicable to the considered problem.
- With the aid of the ESO, the unmeasured states and the external disturbances are successfully reconstructed, and thereby the proposed Nash equilibrium seeking algorithm cancels the assumption in References 22‐24 that full‐state measurements are available for feedback.
- Compared with the algorithms determined by the communication topology in References 16‐19,22‐24, the proposed seeking strategy drops this drawback by integrating the ADO.
