In this paper we analyze stability properties of multi-agent control system with an artificial potential based on bell-shaped functions. In our approach attractive and repulsive forces created by potential gradient have the same form. This particular property allows definition of target formation that is parameter invariant. Due to the fact that agents are identical, the proposed structure of formation potential is invariant to the interchange of agents configurations, hence, target in which particular agent would eventually end up, depends only on formation initial condition. It has been demonstrated that stability analysis, given for stationary targets, applies to moving targets formation as well. We show that position of unwanted stable equilibria can be controlled by a single parameter that defines an elementary potential function. This fact has been used for synthesis of an adaptation algorithm, such that arrival of agents at required formation is guarantied. Simulation results, presented at the end of the paper, confirm correctness of the proposed control scheme.
