  The protection of quantum states is challenging for non-orthogonal states
especially in the presence of noises. The recent research breakthrough shows
that this difficulty can be overcome by feedback control with weak
measurements. However, the state-protection schemes proposed recently work
optimally only for special quantum states. In this paper, {by applying
different weak measurements, we extend the idea of the state-protection scheme
to protect general states.} We calculate numerically the optimal parameters and
discuss the performance of the scheme. Comparison between this extended scheme
and the earlier scheme is also presented.
