The invention discloses an airplane electro-hydrostatic brake control device and a dynamic control method, and relates to the technical field of brake control systems, the airplane electro-hydrostatic brake control device comprises a controller, a brushless direct current motor, a plunger pump, an energy accumulator, an electromagnetic valve, a safety valve and a hydraulic mechanism; an output shaft of the brushless direct current motor is coaxially connected with the plunger pump and drives the plunger pump to operate, the energy accumulator provides initial pressure for the plunger pump, and the plunger pump is communicated with the hydraulic mechanism through the safety valve and the electromagnetic valve. And the controller performs closed-loop control based on the internal temperature and pressure information of the hydraulic mechanism, the rotating speed information of the brushless direct current motor and the displacement information of the hydraulic mechanism so as to control the electromagnetic valve and the brushless direct current motor to cooperatively drive the hydraulic mechanism. It is guaranteed that the static brake system is switched on when the airplane needs static brake, it is guaranteed that the static brake is not switched on mistakenly when the static brake is not needed, and the safety of the airplane is effectively improved. The takeoff line brake pressure maintaining device is high in efficiency, high in frequency response and capable of maintaining takeoff line brake pressure. And the brake pressure can be quickly and accurately controlled.
