“…Other noteworthy extensions which appeared in the formation control are self tuning control [5], adaptive control [6]- [9], gain scheduling control [10], linear quadratic Gaussian control [11], nonlinear tracking control [12]. In order to solve the consensus tracking control problem, a great deal of algorithms were developed, i.e., linear conventional PD/PID control [13], the method of leader-follower [14], [15], backstepping control [16], integrator backstepping method [17], output-feedback tracking controllers [18], dynamic surface control technique [19], genetic algorithm based control [20], sliding mode control [21], [22], and approach of graph theory analysis [23]. From the existing literature review, it has been investigated that graph theory analysis has great advantages for dealing with distributed control problem because it can simplify communication topology and optimize information model of multi-AUV system.…”
