| Abstract | a = radius of the circular orbit, m B = Earth magnetic field, T Ex1y1z1 = inertial geocentric frame, with origin at Earth’s mass center FA, FB = components of the control force, N FC = control force, N G = system center of mass Gxyz = orbital frame with origin at G Gx1y1z1 = moving frame with origin at G and axes parallel to those of Ex1y1z1 HG = central angular momentum of the system, kg m=s h = distance from the upper end, m hG = distance between m2 and G, m I = interval min; max Ie h = tether current profile, A Is = central moment of inertia about a line perpendicular to the tether, kg m IG = central inertia tensor of the system i = orbital inclination, rad i; j; k = basis of the orbital frame, Gxyz i1; j1; k1 = basis of the inertial frame, Ex1y1z1 J1 = R L 0 hG h Ie h dh, A m k, k1, k2 = feedback control gains L = length of tether, m MC = gravitational torque about G, N m ME = Lorentz torque about G, N m MG = control torque about G, N m m = total mass of the system m1 m2 mt , kg mt = tether mass, kg m1 = lower-end mass, kg m2 = upper-end mass, kg R, R1, R2 = parameters of the extended control method t = time, s u = unit vector along the tether u2 = sin i cos k, unit vector in orbital plane, perpendicular to tether line |
