Wave power generation system based on fuzzy control

Abstract

The invention relates to a wave power generation system based on fuzzy control. The wave power generation system based on the fuzzy control comprises a mechanical power device, a control device, a power generation device and a rectification and energy storing device. The mechanical power device comprises a hydraulic cylinder, a floater, a connecting rod and a waved plate, the connecting rod is connected with the floater and connected with the waved plate simultaneously, the internal space of the hydraulic cylinder is divided into upper and lower space bodies by the waved plate, and the space bodies are filled with fixed amount magnetorheological fluid and are connected with a magnetorheological fluid pipeline separately. By adopting the fuzzy control technology, according to a time-varyingcharacteristically dynamic system of the wave power generation system, the modern fuzzy control technology is applied, a series of rules subsumed according to actual conditions of influence factors are stored in a computer, fuzzy set theory quantification is used for realizing the intelligent operation of the rotating speed of a generator adjusted and controlled by an electromagnetic coil current, and continuable and stable power generation is realized while the power generation system is protected to work safely under bad weather.

Description

technical field [0001] The invention relates to the technical field of ocean wave power generation, in particular to an ocean wave power generation system based on fuzzy control. Background technique [0002] With the continuous development of society and economy, and the rapid expansion of population, the energy consumed by human beings is also increasing. However, as we all know, the energy reserves of the entire earth are limited. Since the first oil crisis in 1973, people have paid more and more attention to the development and utilization of renewable energy. At present, the development and utilization of renewable new energy, so that its own energy structure can be adjusted, in order to achieve sustainable energy development and meet human needs for energy, has reached a consensus in countries around the world. [0003] The ocean area accounts for about 70% of the global area, and according to statistics in the article "Ocean Energy Development" published by UNESCO, t...
