The invention discloses a pressure closed-loop control system for an electro-hydraulic pressure servo valve of an aircraft braking system. The pressure closed-loop control system comprises a braking instruction sensor, an FPGA module, a DSP module, a pressure sensor and the electro-hydraulic pressure servo valve. The FPGA module is connected with the DSP module, the brake instruction sensor, the pressure sensor and the electro-hydraulic pressure servo valve. By adopting the incremental PID algorithm and adding the transparent transmission link, the response speed and the control precision of the system are effectively improved, and meanwhile, the problem of brake failure caused by the fault of the pressure sensor is avoided. According to the method, the command pressure change can be quickly responded, and accurate control of the brake pressure is ensured, so that the brake efficiency is improved, the risk of uneven temperature of a brake disc of an aircraft wheel and aircraft yawing is reduced, and the reliability and the safety of an aircraft brake system are enhanced.
