H∞ Control for Impulsive Disturbances: A State-Space Solution
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 ...
Affine Frames of Rational Wavelets in H2 (II+)
In this paper we investigate frame decompositions of H2(II+) as a method of constructing rational approximations to nonrational transfer functions in H2(II+). The frames of interest are generated from a single analyzing ...
Motion Control and Coupled Oscillators
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 ...
Analysis of a complex activator-inhibitor equation
Basic properties of solutions and a Lyapunov functionalare presented for a complex activator-inhibitor equation witha cubic nonlinearity.Potential applications include control of coupled-oscillator arrays(for quasi-optical ...
Computation for Nonlinear Balancing
We illustrate a computational approach to practicalnonlinear balancing via the forced damped pendulum example.
Control Problems of Hydrodynamic Type
It has been known for some time that the classical work of Kirchhoff, Love,and Birkhoff on rigid bodies in incompressible, irrotational flows provideseffective models for treating control problems for underwater vehicles.This ...
Nonlinear Model Reduction for RTCVD
In this paper, we examine alternative methods for reducing thedimensionality of nonlinear dynamical system models arising incontrol of rapid thermal chemical vapor deposition (RTCVD) forsemiconductor manufacturing. We focus ...
Computing Balanced Realizations for Nonlinear Systems
This paper addresses the problem of computability pertaining to the Scherpen(1994) theory and procedure for balancing of nonlinear systems. In contrastto Moore's (1981) balancing method for linear systems, the Scherpen ...
Efficient Implementation of Controllers for Large Scale Linear Systems via Wavelet Packet Transforms
In this paper we present a method of efficiently implementing controllers for linear systems with large numbers of sensors and actuators. It is well known that singular value decomposition can be used to diagonalize any ...
A Model for a Thin Magnetostrictive Actuator
In this paper, we propose a model for dynamic magnetostrictive hysteresisin a thin rod actuator. We derive two equations that representmagnetic and mechanical dynamic equilibrium. Our model results from an application of ...
