Robust safety formation control for multiple unmanned helicopters

2020 IEEE 16th International Conference on Control & Automation (ICCA), 2020
The fully distributed robust formation control of unmanned helicopters (UHs) with external disturbances and model uncertainty capability is investigated. In the position loop and the attitude loop, continuous fast robust controllers are proposed, and an integral filter is introduced between two loop.

Adaptive control strategy for an unmanned helicopter

2015 34th Chinese Control Conference (CCC), 2015
The unmanned helicopter (UH) handling qualities design is a challenging task since the vehicle dynamics subject to parametric uncertainties and measurement noise. This paper presents an adaptive control scheme with error compensation that can achieve significant tracking performance.

Improved design of clutch control system of unmanned helicopter

2017 IEEE International Conference on Information and Automation (ICIA), 2017
In light of starting clutch control requirement in unmanned modified process of a helicopter, the control system with high-reliability circuit, excellent engagement quality and engine speed stability are researched. By analysing the disadvantantages of the original clutch control system, the improved design requirements are proposed.

Linear Tracking Control for Small-Scale Unmanned Helicopters

IEEE Transactions on Control Systems Technology, 2012
This paper presents a model-based tracking control design for small-scale unmanned helicopters. The design objective is for the helicopter to track predefined inertial position (or velocity) and heading reference trajectories. The controller is based on a nominal linear state-space model that successfully captures the small-scale helicopter coupled ...

Control system design of a small-scale unmanned helicopter

IEEE ICCA 2010, 2010
This paper investigates the control design of a small-scale unmanned helicopter. We fulfill the development of modeling with the prediction error method, and control system with PID and robust control method, and eventually accomplish the hardware-in-the-loop simulation system and flight test.

Synchronized altitude tracking control of multiple unmanned helicopters

Proceedings of the 2010 American Control Conference, 2010
In this paper, we consider the synchronized altitude tracking control for multiple helicopters, when the desired trajectory is only available to the leaders. By using the weighted average of the neighbors' states as the reference signal, the adaptive neural network (NN) tracking control is designed for each helicopter.

Vision-based Autonomous Landing Control for Unmanned Helicopters

Journal of Intelligent & Robotic Systems, 2017
This paper presents the design of a complete control system for the autonomous landing of unmanned flybarless helicopters on known stationary visual landmarks. A state estimator based on the complementary filters notion, estimates the position, translational velocity and attitude vectors of the vehicle by fusing data acquired from the on–board camera ...

Model Predictive Control for an Unmanned Helicopter

2019 IEEE International Conference on Unmanned Systems (ICUS), 2019
Helicopter is a very interesting MIMO plant with strong nonlinearity and coupling properties. This article implements a controller for helicopter based on the cascade control strategy. A discrete model predictive controller(DMPC) using Laguerre functions is proposed for velocity tracking, and an active disturbance rejection controller is presented for ...
