Abstract

Based on the non-linear characteristics of twin flapper-nozzle servo valve, the equation was deduced, and a nonlinear mathematical model was set up. By using of the non-linear control theory, the local input-output linearization of the system was analyzed by the input-output precision linear. Finally, the results of simulation and experimentation approved the strong advantages of the proposed model. The results are useful for the high-precision position tracking control of the electro-hydraulic servo valve control system.
