Smooth and Analytic Normal Forms: A Special Class of Strict Feedforward Forms
In this paper we prove that any smooth (resp. analytic) strict feedforward system can be brought into its normal form via a smooth (resp. analytic)...

Flatness Based Approach to a Heat Conduction Problem in a Crystal Growth Process
A nonlinear heat conduction problem from crystal growth technology is considered. The growth process studied comprises two phases (solid crystal and...

Observers as Internal Models for Remote Tracking via Encoded Information
In this paper, we consider a servomechanism problem in which the command and control functions are distributed in space, and hence the system...

Vehicle Path-Following with a GPS-aided Inertial Navigation System
This article describes a methodology to guide a passenger car along a predefined path in order to perform drive tests. A feedback/feedforward control...

Flatness-Based Improved Relative Guidance Maneuvers for Commercial Aircraft
With the sustained increase of air traffic leading to airspace saturation, new flight maneuvering capabilities are expected for commercial aircraft....

Closed-Loop Fault-Tolerant Control for Uncertain Nonlinear Systems
We are designing, perhaps for the first time, closed-loop fault-tolerant control for uncertain nonlinear systems. Our solution is based on a new...

Remarks on Moving Horizon State Estimation with Guaranteed Convergence
In this paper, a moving horizon state estimation scheme is proposed. The scheme is inspired by combining the system-theoretic concept of...
-
On Invariant Observers
A definition of invariant observer and compatible output function is proposed and motivated. For systems admitting a Lie symmetry-group G of...

Model-based Nonlinear Tracking Control of Pressure Swing Adsorption Plants
Pressure swing adsorption (PSA) processes are used for the separation and purification of gas mixtures. PSA plants are composed of several fixed-bed...

8 Entropy Production of Atmospheric Heat Transport
We examine the rate of entropy produced by the atmospheric general circulation and the hypothesis that it adjusts itself towards a macroscopic state...
-
A Imperfection Data Bank
For the stochastic modeling of geometric imperfections as described in Sec. 12.1, a database [5] has been available. This database provides...

10 Thermodynamics of the Ocean Circulation: A Global Perspective on the Ocean System and Living Systems
In this chapter, we investigate thermodynamics in a global-scale open ocean circulation and discuss the physical properties of “living systems”, that...

16 Temperature, Biogenesis, and Biospheric Self-Organization
We argue that the biosphere has evolved deterministically as a selforganized system, given the initial conditions of the Sun-Earth system. With...

7 Rational Treatment of Uncertainties
Structural analysis up to this date, generally is still based on a deterministic conception. Observed variations in loading conditions, material...

4 Finite Element Method
In this chapter, the fundamentals of the displacement-based finite element method are reiterated in a concise form, details can be found in a number...

9 Direct Monte Carlo Simulation
The evaluation of the stochastic response by the Monte Carlo simulation technique is a powerful method for highly nonlinear systems as well as for...

Parametric Spectral Estimation and Data Whitening
The knowledge of the noise Power Spectral Density is fundamental in signal processing for the detection algorithms and for the analysis of the data....

18 Insights from Thermodynamics for the Analysis of Economic Processes
The laws of thermodynamics constrain transformation of materials and energy, and thus have implications for economic processes. This paper provides...

1 Entropy Production by Earth System Processes
Degradation of energy to lower temperatures and the associated production of entropy is a general direction for Earth system processes, ranging from...

11 Random Vibrations of Large Finite Element Systems
The basic idea for the computation of the stochastic response is based on the Karhunen-Loève expansion of the stochastic loading. For each Karhunen-...
