Aiming at the problem of low efficiency of traditional direct drive wave power generation system due to low wave frequency and speed

and avoiding the influence of seawater corrosion and wind wave impact on the power generation device

a linear Hall based maximum power tracking control strategy for direct drive wave power generation is proposed in this paper. The proposed multi-layer permanent magnet embedded cylinder linear generator has high power density and can effectively prevent the damage of the wave impact

while the linear Hall has strong reliability and resistance to seawater corrosion in wave power generation

and can effectively solve the disadvantages of mechanical sensors and sensorless algorithms in the marine application environment. In addition

according to the principle of mechanical resonance

the maximum tracking strategy of wave energy is proposed

and the wave energy conversion efficiency is improved by controlling the float movement to make it in phase with the wave excitation force. Finally

the control strategy simulation and hardware experiment platform of direct drive wave power generation are built. The experimental results are consistent with the simulation results

verifying the effectiveness of the proposed control strategy.
