A Homotopy Continuation Solution of the Covariance Extension Equation
Algebraic geometry plays an important role in the theory of linear systems for (at least) three reasons. First, the Laplace transform turns... -
On Existence and Nonexistence of Limit Cycles for FitzHugh-Nagumo Class Models
In this paper we discuss the existence and non-existence of limit cycles of FitzHugh-Nagumo class models. The purpose is to clarify some unclear... -
From Empirical Data to Multi-Modal Control Procedures
In this paper we study the problem of generating control programs, i.e. strings of symbolic descriptions of control-interrupt pairs (or modes) from... -
Collision Free Motion Planning on Graphs
A topological theory initiated in [4,5] uses methods of algebraic topology to estimate numerically the character of instabilities arising in motion... -
Computing Protein Structures from Electron Density Maps: The Missing Fragment Problem
Rapid protein structure determination relies greatly on the availability of software that can automatically generate a protein model from an... -
Control Applications of Sum of Squares Programming
We consider nonlinear systems with polynomial vector fields and pose two classes of system theoretic problems that may be solved by sum of squares... -
LMI Optimization for Fixed-Order H∞ Controller Design
A general H∞ controller design technique is proposed for scalar linear systems, based on properties of positive polynomial matrices. The order of the... -

A Qualitative Approach for Symbolic Data Manipulation Under Uncertainty
In decision making problems, the experts knowledge has different natures: numerical, interval-valued, symbolic, linguistic, . . . In other terms, the... -
4. Stability of Nonlinear Switched and Impulsive Systems
In this chapter, we shall study the stability of nonlinear switched and impulsive systems of the form... -
4 Continuous-time Systems: Tracking Control
In this chapter we treat the problem of H∞ tracking with stochastic multiplicative white noise. We extend the work of [98], which does not involve... -
Stability
This chapter is devoted to the study of the stability for singular systems in both the continuous and discrete contexts. The definitions of... -
H∞ Filtering
The H∞ filtering problem for state-space systems has received much attention in the past two decades. In the H∞ setting, the noises are assumed to be... -
Control of Nonlinear Systems with Uncertainty
In this chapter, we consider nonlinear systems with time-varying uncertain variables and present robust inverse optimal controller designs that... -
5 Case Studies
This section demonstrates our hybrid estimation scheme on the basis of the illustrative 3-component cPHA and the BIO-Plex process automation example... -
An Efficient QR Algorithm for a Hessenberg Submatrix of a Unitary Matrix
We describe an efficient procedure for implementing the Hessenberg QR algorithm on a class of matrices that we refer to as subunitary matrices. This... -
Arithmetic Properties of Observable Time Dependent Systems
Here we consider questions of discrete observability for linear systems of ordinary differential equations, extending work by Martin and Smith in...
