Based on the introduction of a new type of multi-point direct-drive wave power generation system and energy conversion process, the principle of the system based on power electronic DC-DC converter and rectifier to make the system run at regulated voltage and constant speed is analyzed. The fuzzy neuron PID control method is applied to the intelligent control process of the system. The computer simulation model is set up and a laboratory test platform is set up to analyze the operation of the system under the condition of regular wave and irregular wave input. Simulation analysis and test results show that the described control device and the control principle can effectively suppress the fluctuation of energy input of the wave power generation system and realize the stepless regulation of the generator rotor speed with good control performance.
