This paper consider a standard consensus algorithm under output saturations. In the presence of output saturations, global consensus can not be realized due to the existence of stable, unachievable equilibrium points for the consensus. Therefore, this paper investigates necessary and sufficient initial conditions for the achievement of consensus, that is an(More)
— In this paper, we consider a formation keeping problem for a satellite formation flying system. The relative motion dynamics is designed with polytopic uncertainties by considering elliptical reference orbit, noncoplarnar formation and unknown angular rate, angular acceleration within some boundary. We propose a composite nonlinear feedback control law(More)
