Modified backstepping control of Quadrotor
International Multi-Conference on Systems, Sygnals & Devices, 2012In this paper, a modified backstepping approach will be developed and applied to control unmanned areial vehicles (UAVs), Quadrotor. In this modified backstepping approach, the number of control parameters is reduced by half compared with the classical back stepping approach used in the literature.

Controlling chaos via backstepping design
Physical Review E, 1997In this Brief Report a method is presented to achieve both stabilization of chaotic motion to a steady state and tracking of any desired trajectory. The proposed approach is based on backstepping design and consists in a recursive procedure that interlaces the choice of a Lyapunov function with the design of feedback control.

Decentralized Neural Backstepping Control
2017This chapter deals with trajectory tracking for a class of discrete-time decentralized nonlinear systems. A high order neural network is used to approximate a decentralized control law designed by the backstepping technique as applied to a block strict feedback form. The neural network learning is performed on-line by extended Kalman filtering.

Backstepping-based adaptive PID control
IEE Proceedings - Control Theory and Applications, 2002This paper addresses analysis and design issues in adaptive PID control for linear second-order minimal phase processes using the backstepping algorithm. The first step consists in adding an integral action to the basic backstepping algorithm to obtain a zero static error..

Adaptive observer backstepping control using neural networks
IEEE Transactions on Neural Networks, 2001This paper extends the application of neurocontrol approaches to a new class of nonlinear systems diffeomorphic to output feedback nonlinear systems with unmeasured states. A neural-based adaptive observer is introduced for state estimation as well as system identification using only output measurements during online operation. System identification is

Passive control of backstep flow
Experimental Thermal and Fluid Science, 1998Abstract The passive control of turbulent flow downstream of a backward-facing step using a permeable reattachment surface is described. An impermeable reattachment surface leads to the upstream convection of rotational fluid and pressure disturbances which is absent when a permeable surface is used.

ADAPTIVE BACKSTEPPING CONTROL OF UNCERTAIN LORENZ SYSTEM
International Journal of Bifurcation and Chaos, 2001In this paper, we consider the problem of controlling chaos in the well-known Lorenz system. Firstly we show that the Lorenz system can be transformed into a kind of nonlinear system in the so-called general strict-feedback form. Then, adaptive backstepping design is used to control the Lorenz system with three key parameters unknown.

Observer-Based Backstepping Controller for Microalgae Cultivation
Industrial & Engineering Chemistry Research, 2013Microalgae are microscopic plants that exist in an aquatic environment. They are involved in the production of high value compounds and also have applications in energy production. In this work, the regulation of biomass concentration in a bioreactor is investigated by using an observer-based backstepping control approach.

Singularity-free backstepping controller for model helicopters
ISA Transactions, 2016This paper develops a backstepping controller for model helicopters to achieve trajectory tracking without singularity, which occurs in the attitude representation when the roll or pitch reaches ±π2. Based on a simplified model with unmodeled dynamics, backstepping technique is introduced to exploit the controller and hyperbolic tangent functions are ...
