  7. Abstract:
  8. Problems of global warming have motivated energy communities to design and develop green power generators. Energy of the ocean waves is one of the most fascinating clean energies which have not been completely explored yet. The present work intends to design and develop a novel efficient system to generate electricity using the power of ocean waves. The proposed device can operate in most ocean situations. The device floats with the buoyancy of the buoy over the ocean surface. Regarding the ocean inputs the device is sinking or floating at the ocean to control and optimize input force. In the proposed system kinetic energy of the ocean wave is converted into force. This force moves the hydraulic system and generates power. The power generated by the device has to be optimized during the device operation. A fuzzy logic controller monitors this significant job during the device operation. Hurricanes are one of the most destructive situations that a wave energy converter can be dealing with. The most significant role of the fuzzy logic controller is to survive the device under the harsh of ocean. The performance and functionality of this novel system is highly enhanced as the use of many mechanical elements such as gear boxes, springs and electronic devices are eliminated. Therefore, in6operation problems such as corrosion, miss6lubrication and electrical short circuiting due to humidity are significantly reduced due to the novel design. This thesis has concluded that the proposed device can efficiently convert ocean wave energy into electricity. Generated electrical power of the device for a normal wave (1m height, 1rad/sec) is around 120 watts. The simulation showed that the fuzzy logic controller implication on the device was successful as it can control the device over all of the none6 operative situations
