Problems solved by technology

Active compensation relies on the piston movement of the hydraulic cylinder to counteract the wave heave. This device has high control accuracy, but consumes a lot of energy
Semi-active compensation is to rely on the platform to compress the accumulator to store energy to offset the wave heave as the wave rises. The control accuracy of this device is not high, and the energy consumption is small

Abstract

The invention designs a sea wave active compensation system of a hybrid mechanism. The sea wave active compensation system of the hybrid mechanism can detect a posture and a displacement of a maintenance ship after the maintenance ship is affected by sea waves, and active compensation of the sea waves can be achieved by controlling the hybrid mechanism. The sea wave active compensation system of the hybrid mechanism includes a hybrid mechanism, a detection system, a motion control system and an electric system; the hybrid mechanism includes an upper platform and a six-freedom degree parallel platform, and is an execution mechanism of the sea wave active compensation system, and an execution element adopts a hydraulic cylinder and a hydraulic motor; the detection system is used for detecting a position and a posture change parameter of the ship and a state parameter of the hybrid mechanism, and providing control information feedback for the control system; the motion control system canprovide real-time control quantity for the hybrid mechanism according to the parameters detected by the detection system through model calculation and motion control computing; and the electric systemcan provide a stable energy electric power for the whole mechanism, and can achieve man-machine information connection and system parameter real-time monitoring and so on.

Description

technical field [0001] The invention relates to the technical field of underwater robots, in particular to an active wave compensation system of a hybrid mechanism. Background technique [0002] Wind power generation is one of the power generation methods with the most mature technology, the most developmental conditions and the most promising development prospects in the field of new energy. All countries regard it as the most important part of the new energy strategy. my country is rich in offshore wind energy resources, with an installed capacity of about 200 million kilowatts in areas within the water depth of 5 to 25 meters in the offshore, and there are even more abundant wind resources in the far sea. The development of offshore wind turbines is limited by one of the conditions: the lack of professional installation ship resources, and the high cost and risk of offshore construction. The state pays close attention to the development of offshore wind power, and has is...
