Abstract

A control system for controlling displacement of the aerodynamic control-surfaces (10) of an aircraft in response to movement of the pilot's control column (18). The system includes a first processor (16) that is supplied with input signals from the pilot's control column (18) and also with predominantly lower-frequency components of feedback signals from the control- surfaces (10). The first processor (16) derives an intermediate signal from the input signal and the feedback signal components by digital processing and supplies this intermediate signal to a second processor (25) which also receives the predominantly higher-frequency components of the feedback signal. The second processor (25) derives an output signal from the intermediate signal and the feedback signal components by analogue processing and supplies this to an actuator (14) for controlling displacement of the control-surfaces. The system may include a plurality of first and second processors arranged to provide a degree of redundancy. <IMAGE>
