Reliable and efficient wave energy measurement and control system has practical significance for the development and utilization of wave energy. In this paper, a set of wave energy measurement and control system was designed by combining the NI CompactRIO embedded system and LabVIEW software platform. First, the wave energy measurement and control system needs analysis and overall design, the corresponding hardware system is builded according to the overall structure of the block diagram and the various hardware configuration and circuit are introduced and designed. Then, LabVIEW is used to write the system software program, including data acquisition module, data storage module, data playback module and PWM current control module. Finally, the reliability and practicability of the wave energy measurement and control system are verified by PWM current control experiment. The experimental results show that the system is simple to operate, has a friendly interface and can monitor the wave energy in real time and can track the maximum power point in some degree.
