The invention discloses an optimization method capable of realizing
spinning-stabilized unfolding of tethered formation by using a continuous
propeller and belongs to the field of
spacecraft guidanceand control. The implementation method comprises the steps of defining different reference coordinate systems to describe movement of a tethered formation
system and building a dynamical model of thespinning-stabilized tethered formation
system by utilizing the Lagrange equation; describing a
finite time domain
optimal control problem in a real-
time domain, then converting the control problem into a Mayer form based on the
time domain mapping, giving control input and
state variable constraint for the dynamical model of the
spinning-stabilized tethered formation
system and building an optimalunfolding model of the
spinning-stabilized tethered formation system; and scattering the final state of spinning-stabilized unfolding of the tethered formation system and the control input to a series of
discrete points by utilizing the Legendre-Gauss
discretization method. As numerical solution for the dynamics process of the spinning-stabilized unfolding of the tethered formation system is carried out by using the
Gaussian pseudo-spectral method, parameters required to be input can be reduced and the calculation precision is improved.
