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.
