Robust control allocation with adaptive backstepping flight control

Proceedings of the Institution of Mechanical Engineers, Part G: Journal of Aerospace Engineering, 2013
For the enhancement of survivability and maneuverability, modern aircraft systems have redundant control effectors. Control allocation is a useful method for distributing control signals among the individual effectors. In order to implement a control allocation scheme, the control system is designed using two-step procedures.

ADAPTIVE BACKSTEPPING CONTROL OF A CLASS OF CHAOTIC SYSTEMS

International Journal of Bifurcation and Chaos, 2000
This paper is concerned with the control of a class of chaotic systems using adaptive backstepping, which is a systematic design approach for constructing both feedback control laws and associated Lyapunov functions. Firstly, we show that many chaotic systems as paradigms in the research of chaos can be transformed into a class of nonlinear systems in

Robust adaptive backstepping control of micro-turbines

2016 Chinese Control and Decision Conference (CCDC), 2016
Micro-turbine (MT) is characterized with fast response and high efficiency, thus is an ideal candidate to be included in the hybrid renewable energy generation systems. However, MT exhibits rather complex dynamics, bringing about technical challenge in control design and stability analysis.

Integrated adaptive backstepping attitude control of spacecraft

2017 IEEE 4th International Conference on Knowledge-Based Engineering and Innovation (KBEI), 2017
In this paper, a nonlinear adaptive backstepping Lyapunov-based controller is designed for spacecraft. Using the Lyapunov theory, the integrated adaptive backstepping controller proves the system's stability. Moreover, the tuning functions are defined by which the stability conditions are satisfied.

Block Backstepping for Adaptive Nonlinear Control *

IFAC Proceedings Volumes, 1995
Abstract We formulate a new design tool for adaptive nonlinear control, called block backstepping. Instead of backstepping a single integratorat a time, this tool allows us to backstep a whole nonlinear block which has relative degree one and bounded-input-bounded-state stable zero dynamics, with respect to appropriately defined inputs and outputs ...

COMPUTING ADAPTIVE BACKSTEPPING CONTROL LAW USING MAPLE

IFAC Proceedings Volumes, 2006
Abstract The backstepping-based adaptive tuning functions design is a control scheme for uncertain systems that ensures reasonably good stability and performance properties of the closed loop. The complexity of the control algorithm makes inevitable the use of digital computers to perform the calculation of the control law.

Adaptive Backstepping Control of an Electrohydraulic Actuator

IEEE/ASME Transactions on Mechatronics, 2014
This paper presents an adaptive position control for a pump- controlled electrohydraulic actuator (EHA) based on an adaptive backstepping control scheme. The core feature of this paper is the combination of a modified backstepping algorithm with a special adaptation law to compensate all nonlinearities and uncertainties in EHA system. First of all, the

Adaptive intelligent backstepping controller of induction machines

2016 8th International Conference on Modelling, Identification and Control (ICMIC), 2016
This paper presents an adaptive fuzzy backstepping controller (AFB) to handle the speed tracking problem of induction machines with unknown model, uncertain load-torque and nonlinear friction. The proposed AFB scheme uses adaptive fuzzy systems to reasonably approximate the uncertain dynamics appearing in the induction machine model.

Backstepping-based adaptive control for underactuated systems

International Journal of System Control and Information Processing, 2015
A backstepping-based adaptive control scheme is presented for uncertain underactuated systems. On the basis of backstepping approach, virtual control components are first constructed and final control term is then derived by defining an integrated error surface.

Adaptive backstepping control for a convertible UAV

2015 Workshop on Research, Education and Development of Unmanned Aerial Systems (RED-UAS), 2015
This paper focuses on a convertible unmanned aerial vehicle (CUAV) whose main characteristics is to perform hover flight for launch or recovery, and horizontal mode during cruise. The dynamic model is obtained using the Newton-Euler approach and it considers the aerodynamic effects.
