Research on Simulation of Aircraft Electric Braking System

More/all electric aircraft (M/A EA) technology is considered to be the future development trend in the aviation industry. However, Aircraft Anti-skid Braking System (ABS) is a key subsystem of M/A EA. With the background of the development of ABS, an aircraft electric braking system is designed to be used in ABS. The paper describes the principles of the work and the features of the aircraft electric braking system, mainly focusing on the motor of the actuating section used in electric braking system. According to the analysis result, the actuating section—math model of the Electro-Mechanical Actuator (EMA) has been established and simulated in MATLAB/SIMULINK. Furthermore, based on the features of the electric braking system, dual-channel model of the whole ABS has been established and studied. The results of the simulation indicates that: the performances of the designed electric braking system gains an advantage over hydraulic braking system obviously; it can reflect the real braking process the aircraft, and the model of the whole system is correct and reasonable.
