The application of dynamic system in the living organism is very instructive. The swimming of micro-organism, sea urchin spermatozoa, by flagellar propulsion is employed for the simulation study to discuss the control parameters for propulsion. The model consists of the arc units connected in series and each unit was approximated by multilink system. The movement of the model by flagellar propulsion was simulated based on the force coefficient introduced by Gray and Hancock. The movement of the model was determined by the function of curvature of each arc unit. Simulated velocity and efficiency of straight swimming were similar to the results of previous studies. The change of propulsion direction was simulated. The control parameters of curvature of arc unit which were proportional to the curvature of the track of swimming were obtained. The velocity and efficiency along the tracks had little difference with various radies of curvatule of the tracks.
