The leader trajectory can be any sufficiently smooth signal, either feasible or nonfeasible. This includes but not limited to a fixed point, a trimming trajectory, and the one that does not satisfy the nonholonomic constraint as robots in question do. To compensate for the effects that only a subset of follower robots has connected to the leader, we develop a distributed observer to estimate the leader’s position and velocities. Using leader’s estimated states, we convert formation errors into an augmented system with external oscillator states, which introduce an additional control variable and overcome the difficulties caused by underactuation. Subsequently, an adaptive tracking control law dealing with model uncertainties and stabilizing the augmented system is proposed, ensuring that formation errors are globally uniformly ultimately convergent to arbitrarily small balls near the origin. Simulation results are performed to validate the proposed control design.<br class="zbmathjax-paragraph">{© 2020 John Wiley & Sons Ltd}</div> <div class="clear"></div> <br> <div class="citations"><div class="clear"><a href="/?q=rf%3A7757404">Cited in <strong>7</strong> Documents</a></div></div> <div class="classification"> <h3>MSC:</h3> <table><tr> <td> <a class="mono" href="/classification/?q=cc%3A93C40" title="MSC2020">93C40</a> </td> <td class="space"> Adaptive control/observation systems </td> </tr><tr> <td> <a class="mono" href="/classification/?q=cc%3A93A13" title="MSC2020">93A13</a> </td> <td class="space"> Hierarchical systems </td> </tr><tr> <td> <a class="mono" href="/classification/?q=cc%3A93A16" title="MSC2020">93A16</a> </td> <td class="space"> Multi-agent systems </td> </tr><tr> <td> <a class="mono" href="/classification/?q=cc%3A93C85" title="MSC2020">93C85</a> </td> <td class="space"> Automated systems (robots, etc.) in control theory </td> </tr><tr> <td> <a class="mono" href="/classification/?q=cc%3A70F25" title="MSC2020">70F25</a> </td> <td class="space"> Nonholonomic systems related to the dynamics of a system of particles </td> </tr></table> </div><div class="keywords"> <h3>Keywords:</h3><a href="/?q=ut%3Aadaptive+tracking">adaptive tracking</a>;
