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......

Multivariable adaptive output-feedback control
Tập 5 - Trang 3413-3418 vol.5 - 2002
In this paper, a new model reference adaptive output feedback controller is proposed for general multi-input multi-output (MIMO) systems with unknown parameters such that the tracking errors as well as the control gains remain uniformly bounded. First an adaptive observer is designed to estimate the state variables and system parameters from input-output data. Then a linear combination of the esti......

A new type of multidimensional coprimeness and its application to finite spectrum assignment for delay systems
Tập 4 - Trang 2779-2785 vol.4 - 2002
This paper presents a new coprimeness over multidimensional polynomial matrices, which only one variable is given a priority to the others. Its application to delay systems, finite spectrum assignment for systems with non-commensurate delays, is also presented.

Modeling, analysis and design tools for dual-rate systems
Tập 5 - Trang 4116-4121 vol.5 - 2002
This paper is concerned with dual-rate sampled-data systems modeled as dual-rate discrete systems. We assume that the continuous-time system has been already designed in order to meet continuous time-domain and frequency-domain specifications. Based on the lifting technique, dual-rate high-order-holds and discrete equivalent models are obtained. Dual-rate models are computed based on dual-rate hig......

Nanoradian digital stabilization of a suspended table for scientific experiments
Tập 6 - Trang 4946-4947 vol.6 - 2002
Digital control design of a suspended table for scientific experiments is presented. The problem was suggested by an experiment to measure the universal gravitational constant G. It requires two residual rotations of the table with respect to the horizontal plane to be kept below 1 nrad. The problem was tackled by assuming a 2D inclinometer and accelerometers as transducers. As actuators, linear e......

Control analysis for non-axisymmetric resistive wall mode stabilization in the DIII-D tokamak
Tập 5 - Trang 3790-3795 vol.5 - 2002
Control schemes and sensor types for the nonaxisymmetric resistive wall mode (RWM) stabilization in the DIII-D tokamak are compared. The analysis is based on a system response model for the RWMs in DIII-D and the modelling uses a toroidal current sheet to represent the plasma surface and a combination of helical and circulating "picture frame" currents to represent the conducting structure. The in......

The scaled unscented transformation
Tập 6 - Trang 4555-4559 vol.6 - 2002
This paper describes a generalisation of the unscented transformation (UT) which allows sigma points to be scaled to an arbitrary dimension. The UT is a method for predicting means and covariances in nonlinear systems. A set of samples are deterministically chosen which match the mean and covariance of a (not necessarily Gaussian-distributed) probability distribution. These samples can be scaled b......
