To control a quantum system, recently the coherent feedback method has attracted wide attention thanks to its several advantages over the conventional measurement-based feedback method. However, for nonlinear quantum systems, no systematic guiding principle for designing a coherent feedback controller has been known, while for the measurement case one can employ the so-called quantum non-demolition (QND) feedback method as a systematic strategy. In this paper, we develop a coherent feedback counterpart of this QND-based control strategy. The effectiveness of this proposal is evaluated in some control problems; qubit stabilization and single photon production.
