Research Of Control System For Swaying Of Ship Test Platform

The paper is based on the project "Anti-rolling tank test equipments on the ship" among the country "211" key invested projects, the paper goes on deep analysis and research on motion of rolling and swaying.Firstly, the characteristic of platform is analyzed in the paper.The princple, component,structure, function and technical parameter of platform are introduced.The related technics which are applied to simulation of ship's motion are discussed.Secondly, some kinds of parts of an apparatus are choosed. Mathematical model of swaying system is made. Meanwhile, the system is simulated and designed. The effect of inertia force on performance of swaying system is also analyzed. According to the result of simulation, the conclusion is drawn that effect of inertia force on performance of swaying system is small.Thirdly,hardware includes components of platform,measuring of displaced sensor,data acqusition.The design of software includes realization of real time controlling under Windows Operation System,scheme of running linking to MATLAB.Expanding interface for designing of controller and realization of high-level operation function in graphic-data for user are also included.Finally, This paper designed a kind of PID parameters self-tuning controller based upon blur control.Compared with routine PID, the simulation results show that this kind of control strategy is effective .
