The hardware circuit of the aircraft anti-skid brake system is built with integrated chips such as digital signal processor (TMS320F28335) and high-precision linear frequency conversion chip (LM131). The PD + PBM compound control algorithm based on runway recognition technology is combined with MATLAB code automatic Generate technology for software design. System to achieve the wheel speed signal acquisition, runway identification and anti-skid control and other functions. In order to verify the feasibility of the system design, anti-skid control system combined with semi-physical simulation platform simulation. The experimental results show that the system can adapt to different runway conditions and has good anti-skid braking performance.
