In this paper, we first introduced the original OGY method for controlling chaos of a discrete time dynamical system, and the new numerical algorithm of computing the target unstable orbit embedded in chaotic attractor and the approximately linearized subsystem around it of a continuous time dynamical system for applying the OGY method to control the system's chaotic motion, which is named as model-based OGY chaos control method developed by the authors. Then, we took the repulsive type maglev system for an example to discuss the relationship between the phase selection of Poincare map of a continuous dynamical system and its chaotic vibration controller design by model-based OGY method. The results also showed that the suggested model-based OGY chaos control method is a strong tool for applying OGY method to solve chaos control problems in engineering that can be modeled as continuous dynamic systems.
