A Collocation/Quadrature-Based Sturm-Liouville Problem Solver
(1999)
We present a computational method for solving a class of boundary-value problemsin Sturm-Liouville form. The algorithms are based on global polynomialcollocation methods and produce discrete representationsof the eigenfunctions. ...
Stationary Bifurcation Control for Systems with Uncontrollable Linearization
(1999)
Stationary bifurcation control is studied under the assumption thatthe critical zero eigenvalue is uncontrollable for thelinearized system. The development facilitates explicit constructionof feedback control laws that ...
The Set-Valued Run-to-Run Controller in Semiconductor Manufacturing Processes
(1999)
In semiconductor manufacturing, run-to-run (RtR) control is paid moreand more attention. In this paper a set-valuedRtR control scheme is introduced. Different from conventional RtR controlmethods, the set-valued method ...
Robustness under Bounded Uncertainty with Phase Information
(1996)
We consider uncertain linear systems where the uncertainties, in addition to being bounded, also satisfy constraints on their phase. In this context, we define the ﲰhase-sensitive structured singular value (PS-SSV) of a ...
Noisy Precursors for Nonlinear System Instability with Application to Axial Flow Compressors
(1997)
This dissertation addresses monitoring of nonlinear systems for detection and prediction of incipient instabilities. The analysis and design presented here rely on the influence of noise on system behavior near the onset ...
H∞ Control for Impulsive Disturbances: A State-Space Solution
(1994)
In this paper we formulate and study an interesting (sub) optimal H∞ control problem related to the attenuation of impulsive disturbances to a class of linear systems. Among the motivating factors is the need to study ...
Mixed H2 /H∞ Optimization: A BMI Solution
(1996)
The mixed H2 /H∞ problem arises as one means to achieve robust good performance for a controlled linear time-invariant system. The idea is to achieve H2 optimal performance subject to an H∞ bound as robustness. It has been ...
Characterization of an ETREMA MP 50/6 Magnetostrictive Actuator
(1998)
This report presents the Displacement (Strain)-Current characteristic of an ETREMA MP 50/6 magnetostrictive actuator. This actuator is made of TERFENOL-D and displays giant magnetostriction. The displacement-current ...
Generalized Inverses for Finite-Horizon Tracking
(2000)
Control and communication issues aretraditionally "decoupled" in discussions of decision and controlproblems, as this simplifies the analysis and generally works well forclassical models. This fundamental assumption deserves ...
Motion Control and Coupled Oscillators
(1995)
It is remarkable that despite the presence of large numbers of degrees of freedom, motion control problems are effectively solved in biological systems. While feedback, regulation and tracking have served us well in ...
