Comparison Research on Decoupling Control Of Fin Stabilizer Load System

摘要

Aiming at the coupling of the electro-hydraulic load simulator of fin stabilizer between loading system and the driving system of fin stabilizer,the feed-forward compensation decoupling controller was designed to eliminate surplus force and the decoupling control further which neglects the disturbance of loading system to driving system was researched. And the characteristic of the different decoupling control methods was analysed. According to the simulation result,neglecting the disturbance of the loading system to the driving system slightly influences the performance of control system.However,this can simplify decoupling controller and reduce the complexity of the control system.Compared with the structure invariance principle,this decoupling control method can consider the dynamic characteristic of servo valve efficiently and compensate it
