This paper is to offer a sliding mode fuzzy control (SMFC) method for a dolphin robot to follow some paths in a horizontal plane. In order to describe the dolphin-like swimming, we first derive the dynamic model of the dolphin robot. Then, a line-of-sight (LOS) guidance law is presented to acquire the desired course angle, which relies on the absolute velocity to compensate for the effect of the sideslip angle. Thatafter, a sliding mode controller (SMC) method is constructed to overcome systematic uncertainties and environmental disturbances, and the asymptotic stability of the control scheme is investigated via the Lyapunov stability
theory. Furthermore, a fuzzy logic controller is employed to build the mapping relationship between the outputs from SMC and the actual control signals for the dolphin robot. Finally, both simulations and experiments are presented to validate the effectiveness of the proposed method.
