Abstract
A basic adaptive control scheme for fixed-wing aircraft was modified
for use in controlling the longitudinal motion of helicopters. The
modification required the addition of two additional feedback variables.
Control was applied only to the cyclic pitch input and not to the collective
input. It was assumed that a coefficient, the cyclic-pitch
control effectiveness, would not change sign throughout the flight
envelope.
Analog computer simulation showed that the modified system was
capable of stabilizing the model used. The handling qualities of the
system were not completely satisfactory and further work is necessary.
