Control method of electronic control brake valve for unmanned aerial vehicle

A control method of an electronic control brake valve for an unmanned aerial vehicle comprises the steps that pressure closed-loop control is conducted, the difference value a of a brake instruction and brake pressure is obtained, if the difference value a exceeds a first threshold value range, the electronic control brake valve outputs a first control signal to a brake actuation device, if the difference value b of the first control signal and a drive current signal is obtained, and if the difference value b exceeds a second threshold value range, the electronic control brake valve outputs a second control signal to a brake actuation device. The electric control brake valve outputs a second control signal to the brake actuating device, and if the second control signal does not exceed the first control signal, the second control signal is assigned to the first control signal; the difference value c between the second control signal and the flow of the brake valve element is calculated, if the difference value
