<p>PURPOSE:To provide an automatic flight controller for a fail operational single digital processing system of a simple, light-weight and inexpensive constitution by providing an analog circuit on each control axis to perform the same operation as a digital part for detection of the fault of the digital part to perform the fail passive fault processing by a comparative monitor system and also to attain the reconstruction by an analog back-up circuit. CONSTITUTION:At a digital part 1, an auto-pilot operation and a damper operation are carried out by the digital processing and the auto-pilot and damper command signals are transmitted after the D/A conversion. At an analog part 8, the input and output signals of a rate limiter 11 are compared with each other by a comparator 12 and also an analog damper operation is carried out. Thus the analog damper signal is compared with the damper command signal received from the part 1. When no fault is detected by the comparison, a switch 16 transmits a flight control signal. If a fault is detected, the output of an analog damper operation part 10 is transmitted as a flight control signal.</p> |
