Abstract :
Aimed at electro-hydraulic servo force control system, according to the nonlinear of electric-hydraulic servo valve, to improve the speed of equivalent valve response, we propose the double electric-hydraulic servo valve parallel control, and two servo valve are controlled by their respective controller, the same signal inputs two controller, every valve controller can adopt different structure and parameters. Iterative control is used to the first controller, another using adaptive control. The oretical analysis and simulation results prove the scheme is feasible. And such system doesn´t cost too much, avoiding using expensive big flow electro-hydraulic servo valve, especially being suitable for those who need to locate quickly and whose positioning precision is high.
