Disturbance Rejection for
Small-Scale Helicopters
14.1 Introduction
Small-scale helicopters are very attractive for a wide range of civilian and military
applications due to their unique features. However, autonomous flight for small
helicopters is quite challenging because they are naturally unstable, have strong
nonlinearities and couplings, and are very susceptible to wind and small structural
variations. Many control techniques have been applied to address the autonomous
flight of helicopters including feedback linearization-based control [187], multivari-
able adaptive control [188], neural network ...
