Transition control using multiple adaptive models and an H-infinity controller design
Tập 4 - Trang 2621-2626 vol.4 - 2002
By transition control, it is meant a type of control method that is employed
when the plant transitions from one operating state to another as a result of a
set point change. This work proposes and develops an intelligent adaptive
multiple model approach that simultaneously adapts the model and an H/sub /spl
infin// controller parameters. The method is demonstrated on a non-linear
chemical reactor...

Development of a closed-loop testing method for a next-generation terminal area automation system
Tập 2 - Trang 1325-1330 vol.2 - 2002
A next-generation air traffic decision support tool, known as the active final
approach spacing tool (aFAST), will generate heading, speed and altitude
commands to achieve more precise separation of aircraft in the terminal area.
The techniques used to analyze the performance of earlier generation decision
support tools are not adequate to analyze the performance of aFAST. The paper
summarizes the...

Disturbance rejection for nonlinear systems
Tập 5 - Trang 3484-3489 vol.5 - 2002
Tracking or rejection of unknown exogenous signals with known generating
dynamics is of major concern in feedback control design. Linear feedback control
based on the internal model principle achieves asymptotic performance for linear
systems with linear exogenous signal dynamics. This paper presents a control
design based on the internal model principle to track or reject nonlinear
exogenous sign...

H/sub /spl infin// controller design for discrete-time fuzzy systems using fuzzy weighting-dependent Lyapunov functions
Tập 4 - Trang 3252-3257 vol.4 - 2002
For discrete-time Takagi-Sugeno (TS) fuzzy systems, we propose an H/sub /spl
infin// state-feedback fuzzy controller associated with a fuzzy
weighting-dependent Lyapunov function. In terms of parameterized linear matrix
inequalities (PLMIs), the controller employs not only the current-time but also
one-step-past information on the time-varying fuzzy weighting functions.
Appropriately selecting the...

Optimal control of HIV infection with a continuously-mutating viral population
Tập 5 - Trang 4033-4038 vol.5 - 2002
There has been much discussion in recent years devoted to determining the
optimal methodology for administering anti-viral medication therapies to fight
HIV infection. There are many reasons to seek such an optimal therapy, including
the minimization of drug toxicity and monetary cost. However, there is
increasing recognition that exposure to many anti-HIV medications produces
extremely rapid chan...

Direct RBF neural network control of a class of discrete-time non-affine nonlinear systems
Tập 1 - Trang 424-429 vol.1
Direct adaptive RBF NN control is presented for a class of discrete-time
single-input single-output non-affine nonlinear systems. An implicit function
theorem is used to prove the existence and uniqueness of the implicit desired
feedback control. Based on the input-output model, RBF neural networks are used
to emulate the implicit desired feedback control. The closed-loop is proven to
be semi-glob...

Nonstationary optimal positioning controller design using GA meta-optimization
Tập 4 - Trang 3165-3167 vol.4 - 2002
For positioning control problems of vibration systems, a nonstationary optimal
regulator (NOR) is known as one of the effective control methods. NOR
corresponds to an LQ regulator based on a time-varying criterion function
including time-varying weights. In conventional studies on NOR, the time-varying
weights were determined by iteration of numerical simulation. Taking control
constraints into ac...

Dual-driver standing wave tube: acoustic impedance matching with robust repetitive control
Tập 5 - Trang 3771-3776 vol.5 - 2002
In many applications of acoustic standing wave tubes, for instance
thermoacoustic heat pumping systems, it is desirable to make a shorter tube
operate like a longer standing wave tube at the same driving frequency. The
basic idea here is to reduce the physical length of the tube, and replace the
removed section with a secondary driver. The problem is then to match the
acoustic impedance at the bou...

Performance study of LQG, MCV, and risk-sensitive control methods for satellite structure control
Tập 3 - Trang 2481-2486 vol.3 - 2002
This paper will review the full-state-feedback LQG, minimal cost variance (MCV),
and risk-sensitive (RS) control for infinite time horizon case. In deriving the
solutions of LQG, MCV, and RS control, Hamilton-Jacobi-Bellman equations are
obtained using dynamic programming method. Unlike LQG and RS controllers, a pair
of coupled algebraic Riccati-type equations arises in the solutions of MCV
contro...

It suffices to check only two special vertex matrices in Kronecker space to analyze the robust stability of an interval matrix
Tập 2 - Trang 1266-1271 vol.2 - 2002
This paper addresses the issue of developing a finitely computable necessary and
sufficient test for checking the robust stability of interval matrices and
provides a complete solution to the problem in the form of an improved 'extreme
point' result. The novelty of the proposed solution is that for this special
case of an 'interval matrix' with all its vertices being stable, it suffices to
check o...
