Abstract:
An ocean platform oil cylinder lifting control method and a system. The control method comprises: a controller receives an actual displacement of an oil cylinder ascending or descending acquired by a displacement sensor located on the oil cylinder, and an initial displacement sent by an upper computer is subtracted from the actual displacement to obtain a deviation displacement; and the controller sends the deviation displacement to a servo valve, and the servo valve controls the corresponding deviation displacement of the ascension and descension the oil cylinder. By using the described method, real time adjustment is performed on an oil cylinder according to the error of the oil cylinder ascending or descending, such that the oil cylinder can ascend or descend according to a predetermined displacement, guaranteeing the synchronous movement of each oil cylinder.
