The simulation results. (a) The 1st signal trajectories, \(x_{1}(t)\) (solid line) and \(y_{1}(t)\) (dotted line). (b) The 2nd signal trajectories, \(x_{2}(t)\) (solid line) and \(y_{2}(t)\) (dotted line). (c) The synchronization error trajectories, \(e_{1}(t)\) (dotted line) and \(e_{2}(t)\) (dashed line). (d) The control input trajectory, \(u(t)\)
