“…The main limitation of the designed protocol in all the previous works [14–18, 22–24] is that the agreed position of the agents is a linear function of initial states (e.g., positions, velocities, and higher‐order states) and also coefficients of protocols, which does not necessarily respect the physical constraints of the position. For instance, take the altitude consensus problem in an MAS composed of unmanned helicopters with third‐order dynamics in which the designed protocol may result in negative or too high altitudes which are not accessible by the UAVs.…”
