Research On Synchronous Hydraulic Control Strategy Of Tipping Position

We well known that electro-hydraulic servo system with synchronized nonlinear, parameter variations, interference, and coupling factors make the establishment of mathematical model of electro-hydraulic servo system, the time is difficult to obtain accurate models, these factors caused the controller design difficult. In this paper, has a strong characteristic of robustness of fuzzy sliding mode control and Neural PID control, making it in the control system, such as the electro-hydraulic servo synchronized with a nonlinearity, parameter variation, external disturbance and other characteristics of the controlled object , you can get good results.Using MATLAB software toolbox in Simulink synchronous system mathematical modeling and simulation comparison for the synchronous controller design and analysis theory.The main research content of papers such as:(1)The hydraulic synchronization system describes the current state of development. Postioner by mechanical analysis derived mathematical coupling between synchronous system, establishment of a synchronous control system coupling between the mathematical model and the use of MATLAB software toolbox Simulink were prepared by S-function features of fuzzy sliding mode variable structure and Neural PID control algorithm process. For postioner synchronization system performance analysis exercise to establish a mathematical model.(2)Synchronous system of postioner simulation and analysis of basic properties, making the system have a basic understanding. Analysis of synchronization error affecting some of the basic factors for the control algorithms on the system after the entry of the impact of providing a basis for comparative analysis. (3)Introduced the fuzzy sliding mode control and Neural PID control strategy to determine methods of use, respectively, its dual-motor hydraulic positioner control system of synchronous position synchronization control and synchronous control force, using MATLAB software Simulink simulation results comparative analysis. Analysis of the kind of control algorithm is more suited to the system and the feedback form that is more reasonable.
