An electromechanical braking system includes first and second electromechanical actuator controllers (EMACs) that each independently generate a complete set of drive control signals for an associated set of electromechanical actuators (EMAs). The drive control signals are generated in accordance with an antiskid algorithm to impart antiskid control to the braking of wheels associated with the EMAs. Drive signals for some of the EMAs from the set of EMAs are output by drivers of the first EMAC and drive signals for the other EMAs from the set of EMAs are output by drivers of the second EMAC. Drive control signals from one of the EMACs are used to control output the drive signals for all the EMAs from the set of EMAs, regardless of the EMAC in which the associated drivers are present. The drive control signals from the other of the EMACs are used as a backup set of drive control signals.

Aircraft brake control architecture having improved antiskid redundancy

A system, apparatus and method provide a means for controlling an electric brake actuator. An electromechanical actuator controller (EMAC) is configured to receive first data indicative of a desired braking force, second data indicative of a braking command generated by a brake input device, the second data different from said first data, and third data indicative of a braking mode. Based on the third data, the EMAC selectively uses the first data or the second data to control the actuator.
