Modelling and experimental investigation of carangiform locomotion for control [PDF]
, 1998 We propose a model for planar carangiform swimming based on conservative equations for the interaction of a rigid body and an incompressible fluid. We account for the generation of thrust due to vortex shedding through controlled coupling terms.
