Automatic control method of double-servo-valve electro-hydraulic position system

The invention provides an automatic control method of a double-servo-valve electro-hydraulic position system, and belongs to the technical field of electro-hydraulic position servo control. The methodcomprises the following steps: firstly, selecting and determining a main servo valve and an auxiliary servo valve in the electro-hydraulic position system; performing closed-loop control in a single-valve working mode of an auxiliary servo valve and locking a zero drift compensation value of the auxiliary servo valve, performing closed-loop control by using a double-valve working mode, dynamically calculating an output component of each servo valve by using a segmented variable slope method, and finally calculating a control current of each servo valve according to the range of each servo valve. The parallel control function of the two servo valves is fully utilized, the system response speed in the large stroke is guaranteed, and the system control precision in the steady state is also guaranteed. 本发明提供一种双伺服阀电液位
