Nonlinear path following for unmanned helicopter

2017 IEEE International Conference on Information and Automation (ICIA), 2017
This paper presents a new nonlinear path following control method for unmanned helicopter. The algorithm of the line-of-sight guidance law previously extended by Park is improved to address the control problems of the unmanned helicopter creatively.

Unmanned Helicopters Applied to Humanitarian Demining

2005 IEEE Conference on Emerging Technologies and Factory Automation, 2006
This article covers research work about unmanned helicopters that is being developed by the Portuguese SME Introsys, S.A. in the context of a generic project targeting the development of a multi-robot system for landmine detection. As helicopters are complex multivariable nonlinear underactuated systems with strong coupling in some control loops, they ...

Navigation of an unmanned helicopter in urban environments

2010 11th International Conference on Control Automation Robotics & Vision, 2010
When employing autonomous vehicles, it is desirable to use controllers which can be rigorously shown to always ensure safety is maintained. In this manuscript we compare two approaches for the problem of navigation through environments containing obstacles. The first uses boundary following to maintain an avoidance distance to obstacles, and the second

Development of an Unmanned Helicopter for Vertical Replenishment

Unmanned Systems, 2015
This paper presents an intelligent and robust guidance, navigation and control solution for a rotary-wing UAV to carry out an autonomous cargo transportation mission between two moving platforms. Different from the conventional GPS/INS-only navigation scheme, this solution also integrates sophisticated Lidar and vision systems capable of precisely ...

A Development of Unmanned Helicopters for Industrial Applications

Journal of Intelligent and Robotic Systems, 2008
In contrast to the wide adoption of unmanned aerial vehicles (UAVs) in the military sector, a far less number of successful applications have been reported on civilian side due to high cost, complexities in operation, and conflicts with existing infrastructure, notably the access of civilian airspace.

Development of an intelligent unmanned helicopter

Proceedings of 1995 IEEE International Conference on Fuzzy Systems. The International Joint Conference of the Fourth IEEE International Conference on Fuzzy Systems and The Second International Fuzzy Engineering Symposium, 2002
This paper describes the current status of and recent results from LIFE and the Sugeno Laboratory project on autonomous control of an unmanned helicopter. A fuzzy-logic-based control system has been developed that enables single inputs (e.g. voice commands) to replace the aircraft's normal set of rudder, collective, longitudinal cyclic, and lateral ...

An Experimental Test Bed for Small Unmanned Helicopters

Journal of Intelligent and Robotic Systems, 2008
This paper introduces a custom experimental test bed for the evaluation of autonomous flight controllers for unmanned helicopters. The development of controllers for unmanned helicopters is a difficult procedure which involves testing through simulation at first, and then actual experimentation on real vehicles.

Hierarchical hybrid modelling and control of an unmanned helicopter

International Journal of Control, 2014
In this paper, we propose a hybrid modelling and control design scheme for an unmanned helicopter. This control structure has a hierarchical form with three layers: the regulation layer, the motion planning layer, and the supervision layer. For each layer, a separate hybrid controller has been developed.
