Abstract:An automatic leveling method for four supports hydraulic platform was introduced and the control problem of it was put forward. Aimed at the problem of high nonlinear dynamics and load coupling among channels for platform electro-hydraulic servo system, a design algorithm based on fuzzy self-adapting control was presented. The controller can be designed without accurate model. Simulated results show that the control approach has high precision, strong robustness against load disturbance and good control performance.
Keywords:Hydraulic platform   Automatic leveling   Electro-hydraulic servo system   Fuzzy self-adapting control
