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......

An algebraic approach based on symmetry relations of state space matrices for decoupling the dynamics of a large space structure
Tập 2 - Trang 1336-1341 vol.2 - 2002
In order to design an effective control policy for the 10 m diameter primary mirror of the Grantecan Telescope, the coupling among the segments that compose the mirror through the structure that supports it must be treated. We present the mathematical demonstration of two important results in order to deal with the mirror dynamics decoupling. Those are: 1) the multiplicity of the eigenvalue corres......

H/sub /spl infin// control and parametric controllers for descriptor systems
Tập 6 - Trang 4908-4913 vol.6 - 2002
In this paper, we study the existing problem of an H/sub /spl infin// controller for descriptor systems. One necessary and sufficient condition is presented by means of two generalized algebraic Riccati inequalities. Using the method of linear fractional transformation, the controller is parametrized by the admissible solutions to the Riccati inequalities with free parameter Q, a real-rational sta......

Control allocation in overactuated aircraft under position and rate limiting
Tập 1 - Trang 791-796 vol.1
Existing approaches to control allocation in overactuated aircraft under control input saturation are conservative. This is due to the fact that the solution to the corresponding constrained optimization problem may not be attainable with a chosen control input weighting matrix. On the other hand, there may exist a weighting matrix for which a solution exists under control input constraints. In th......

Distributed parameter thermal controllability-the inverse heat conduction problem in materials processing
Tập 6 - Trang 4967-4972 vol.6 - 2002
This article addresses the inverse heat conduction problem encountered in thermal manufacturing processes. An open-loop control strategy is developed for distributed parameter conduction systems, based on Galerkin optimization of an energy index employing Green's functions. The surface heat input distribution necessary to generate a desired dynamic temperature field inside a solid body, is analyti......

Safety of a decentralized scheme for free-flight ATMS using mixed integer linear programming
Tập 1 - Trang 742-747 vol.1
In this paper we consider policies for free-flight management of air traffic. We consider instantaneous and bounded heading angle deviation as conflict avoidance maneuvers. The corresponding model, resulting in a mixed integer linear programming (MILP) problem allow to solve both conflict detection and conflict resolution problems. The developed algorithm proved successful in a centralized impleme......

Nonlinear adaptive backstepping motion control of linear induction motor
Tập 4 - Trang 3099-3104 vol.4 - 2002
In this paper, we propose a nonlinear adaptive controller and an adaptive backstepping controller for linear induction motors (LIMs) to achieve speed/position tracking. A nonlinear transformation is proposed to facilitate controller design. Besides, the unique end effect of the LIM is also considered and is well taken care of in our controller design. Stability analysis based on Lyapunov theory is......
