Abstract:
1. An aircraft control system comprising: a computation unit that computes a thrust control signal for controlling engine thrust and a deflection angle control signal for controlling control surfaces based on state information indicating a state of an airframe and an operation command signal from a vehicle control unit; an engine driving unit that drives an engine based on the thrust control signal; a control surface moving unit that moves the control surfaces based on the deflection angle control signal; a response adjustment filter that filters the deflection angle control signal to make a response speed of the airframe in response to deflection of the control surfaces almost equal to a response speed of the airframe in response to a change in thrust of the engine responsive to the detection of a control surface malfunction; a control surface failure/damage detection unit that detects that at least one of the control surfaces malfunctions; and wherein the computation unit calculates the thrust control signal and the deflection angle control signal if it is detected that at least one of the control surfaces malfunctions.
