A composite control law for stabilizing a small-scale helicopter during hover flight mode is proposed in this paper. The proposed method is developed by combining the sliding mode control (SMC) and a nonlinear control law. Parameters of the proposed

Purpose This paper aims to propose output feedback-based control algorithms for the flight control system of a scaled, un-crewed helicopter in its hover flight mode. Design/methodology/approach The proposed control schemes are based on H∞ control a

This correspondence deals with the trajectory tracking control of an un-crewed helicopter during hover/low-speed flights. A multi-loop architecture is used in which the inner-loop holds the fast changing dynamics and the outer-loop establishes the tr

The autonomous operation of unmanned helicopters (UHs) is a necessary but challenging task and a topic well attempted by the scientific community. Trajectory tracking is pivotal to the autonomous operation of UH. In this paper, a small scale helicopt

A helicopter during its autonomous missions is considered to be in hover flight condition for very long extent compared to any other flight conditions and they have to hover before any complex maneuvering mode. Hence the analysis of stability and des

The extremely complex helicopter dynamics is converted to a linear time-invariant model representing the hovering flight. Cross-coupling between longitudinal and lateral dynamics during hover is least, which leads to the usual attempt of separation o
