Improved composite adaptive fault‐tolerant control for dynamic positioning vehicle subject to the dead‐zone nonlinearity

open access: yesIET Control Theory & Applications, 2021
In order to tackle the marine practical constraints, for example the actuator faults, the dead‐zone input, an improved composite adaptive neural control algorithm is proposed for dynamic positioning vehicles in presence of the unknown external ...

Fractional order sliding mode control based on single parameter adaptive law for nano‐positioning of piezoelectric actuators

open access: yesIET Control Theory & Applications, 2021
A fractional order sliding mode control (FOSMC) based on single parameter adaptive law for nano‐positioning of Piezoelectric Actuators (PEAs) is proposed.

Dynamical Systems On Three Manifolds Part II: 3-Manifolds,Heegaard Splittings and Three-Dimensional Systems

open access: yes, 2007
The global behaviour of nonlinear systems is extremely important in control and systems theory since the usual local theories will only give information about a system in some neighbourhood of an operating point. Away from that point, the system may have

Some Results on the Boundary Control of Systems of Conservation Laws

open access: yes, 2002
This note is concerned with the study of the initial boundary value problem for systems of conservation laws from the point of view of control theory, where the initial data is fixed and the boundary data are regarded as control functions.

Funnel function‐based asymptotic output feedback control of hydraulic systems with prescribed performance

open access: yesIET Control Theory & Applications, 2021
An asymptotic output feedback controller for the hydraulic systems with model uncertainty compensation and prescribed performance is proposed here, where state observers, funnel function and nonlinear adaptive controller are integrated via backstepping ...

Pinning control of spatiotemporal chaos [PDF]

open access: yes, 1997
Linear control theory is used to develop an improved localized control scheme for spatially extended chaotic systems, which is applied to a coupled map lattice as an example. The optimal arrangement of the control sites is shown to depend on the symmetry

Attenuation of Persistent L∞-Bounded Disturbances for Nonlinear Systems [PDF]

open access: yes, 1995
A version of nonlinear generalization of the L1-control problem, which deals with the attenuation of persistent bounded disturbances in L∞-sense, is investigated in this paper. The methods used in this paper are motivated by [23]. The main idea in the L1-
