Automatic control of the thrust of an aircraft engine may include: (1)
calculating a first difference between a measured speed and a reference speed of
an aircraft to determine an intermediate term and (2) calculating a second difference
between the intermediate term and a previously selected corrector term. If the
second difference is greater than a threshold value, then the intermediate term
is selected as a current corrector term. Otherwise, the previously selected corrector
term is selected. The selected corrector term and an equilibrium term, which produces
an equilibrium rating of the engine in the absence of disturbances, are summed
to produce a control value, and the control value is applied to the engine.
