This paper focus on analyzing and comparing the merits and faults of neural oscillators and dynamics control methods for the physical human-robot interaction. Firstly, the principles of two control modes are introduced about neural oscillators and dynamics. Secondly, their self-oscillation and synchronizatin chracteristics are analyed and compared in both without input and with input cases respectively. Lastly, based on human-robot handshaking interaction, simulation is implemented by using two control methods respctively. And the validity of two control methods are compared and analyzed according to simulation results.
