Abstract

The linear model of valveless electro-hydraulic servo steering device neglects the nonlinear factors, especially the factors of the control subsystem, so the quantitative static and dynamic characteristics of the actual system cannot be evaluated accurately. Aiming at the problem, the steering device for a certain ship is chosen as the studying object and the nonlinear mathematical models of the control subsystem and hydraulic transmission subsystem are derived by a full consideration of the nonlinear factors and the linear factors which are not considered in the linear model. Utilizing the coupling relationship between two subsystems, the nonlinear simulation model is set up in AMESim. By simulation analysis and experimental verification, it is proved that the nonlinear mathematical model in this paper can evaluate the static and dynamic characteristics more accurately, which is of great significance to the design and optimization of the valveless electro-hydraulic servo steering device.
