Based on problem that the magneto rheological damper damping force of aircraft landing gear is not controllable in the process of aircraft's landing and taxiing. A method of embedded buffer controller of aircraft landing gear based on magneto rheological fluid is presented and the buffer control system is designed to control the magneto rheological damper damping force in my article, which mainly includes the selection of embedded digital signal processor（DSP），the principle design of control system, and the design of power generation circuit modules, reset circuit modules, JTAG emulation circuit module, clock oscillator circuit module, A/D sampling correction module, D/A converter module, E2ROM circuit and the voltage controlled current source driver module. Through the simulation of circuit module, the current that is generated by voltage-controlled current source in the control system is acceptable to the MR damper, the magneto rheological buffer controller can control damping force and play a role in adjusting the aircraft landing gear.
