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......

On concentration control of fast reactions in slowly-mixed plants with slow inputs
Tập 6 - Trang 4770-4775 vol.6 - 2002
Fast reactions, taking place in a relatively slowly-mixed environment, are a common phenomenon. In the past, model-based control frequently used Wiener models for such processes. This paper gives a link between first-principle models for processes including arbitrary dynamics of the hydraulics and arbitrary reactions and a Wiener-model description of the same process. The derivation introduces two......

Design of feedforward filters for improving tracking performances of existing feedback control systems
Tập 6 - Trang 4988-4993 vol.6 - 2002
In this paper, we propose a design procedure for feedforward filters that can be used to improve the tracking performance of an existing closed-loop system. Our frequency domain approach does not require a parametric model but only the frequency response of the closed-loop system, which can be measured accurately. It allows the tradeoff between model-matching and control efforts through the select......

Design of controllers for integrating and unstable time delay systems using polynomial method
Tập 4 - Trang 2773-2778 vol.4 - 2002
The paper presents a methodology of the controller design for integrated and unstable time delay systems. The proposed method based on a polynomial approach and LQ control technique yields a class of CT controllers ensuring setpoint tracking as well as load disturbance attenuation. The 2-DOF control configuration is considered. The resulting controllers obtained via polynomial Diophantine equation......

Controllability of twist maps
Tập 6 - Trang 4648-4653 vol.6 - 2002
We study controllability of a class of discrete-time systems arising in Hamiltonian dynamics. In particular, we consider a two-dimensional integrable twist map with time-dependent (control) perturbation. In contrast to the time independent-perturbation case of the Kolmogorov-Arnold-Moser theorem, no invariant structure survives if the perturbation is made a function of time. Using results from erg......

Concepts for constrained control allocation of mixed quadratic and linear effectors
Tập 5 - Trang 3729-3734 vol.5 - 2002
Concepts for new constrained control allocation strategies are developed that deal with systems where moments are nonlinearly related to effector deflections such as those encountered in the case of yawing moment contributions from left-right effector pairs on aircraft.. These concepts are illustrated by considering single and multiple left-right pair effector mixing problems for moments that lie ......

Input shaping for a simple nonlinear system
Tập 1 - Trang 821-826 vol.1
Input shaping is a command modification technique for reducing system vibration that has been implemented successfully on a number of mechanical systems. Input shaping was developed from linear systems theory, but it has been applied successfully to many nonlinear systems. Of the approaches used to shape commands for nonlinear systems, very few address the specific nonlinearities of the systems di......

Efficient moving horizon estimation and nonlinear model predictive control
Tập 6 - Trang 4475-4480 vol.6 - 2002
State estimation from plant measurements should play an essential role in any advanced process control technology. Unlike the model predictive control (MPC) regulator, however, this area has received little attention. In this paper, we address the computational issues surrounding constrained moving horizon estimation (MHE) by presenting an algorithm for the efficient computation of moving horizon ......

Nonlinear model predictive control of a continuous bioreactor using approximate data-driven models
Tập 4 - Trang 2885-2890 vol.4 - 2002
An analytical solution to the nonlinear model predictive control (NMPC) problem is developed for a class of nonlinear systems. Process input-output behavior is captured using Volterra and Volterra-Laguerre nonlinear polynomial models. By employing the traditional 2-norm squared NMPC objective function, the prediction equations, and hence the objective function, are explicitly constructed for an ar......
