      abstract     = {This Letter reports the successful use of feedback from a
                      spin polarization measurement to the revolution frequency of
                      a 0.97  GeV/c bunched and polarized deuteron beam in the
                      Cooler Synchrotron (COSY) storage ring in order to control
                      both the precession rate (≈121  kHz) and the phase of
                      the horizontal polarization component. Real time
                      synchronization with a radio frequency (rf) solenoid made
                      possible the rotation of the polarization out of the
                      horizontal plane, yielding a demonstration of the feedback
                      method to manipulate the polarization. In particular, the
                      rotation rate shows a sinusoidal function of the horizontal
                      polarization phase (relative to the rf solenoid), which was
                      controlled to within a 1 standard deviation range of
                      σ=0.21  rad. The minimum possible adjustment was 3.7
                      mHz out of a revolution frequency of 753 kHz, which changes
                      the precession rate by 26  mrad/s. Such a capability
                      meets a requirement for the use of storage rings to look for
                      an intrinsic electric dipole moment of charged particles.},
