The caudal fin oscillation is generalized by cen- tral pattern generators (CPGs). In this model, the drag coefficient and lift coefficient are the two critical parameters which are obtained by the digital particle image velocimetry (DPIV) and the force transducer experiment. Numerical simulation and physical experi- ments have been performed to verify this dynamic model.展开更多
