There are two different ways of describing uynamicu systems: (i) bymeans of state variables and (ii) by input/output relations. The first method may be regarded as an axiornatization of Newton’s laws of mechanics and is taken to be the basic definition of a system.It is then shown (in the linear case) that the input/output relations determine only one part of a system, that which is completely observable and completely controllable. Using the theory of controllability and observability, methods… Expand

A methodology for the analysis of interacting linear time-invariant dynamical systems is developed and described and its application to interaction analysis of time-variant linear systems and nonlinear systems as well as to synthesis problems is presented. Expand
Feedback realizations in linear multivariable systems
It is shown that redundancy in a feedback system can be expressed as a partial reduction with respect to controllability and observability and this leads to a nice formalism for internally stable control synthesis using rational matrices. Expand

The control of linear time-invariant systems is one of the most basic problems of modern automatic control theory. Although “optimal controllers” which minimize certain costs associated with controlExpand
A Local Characterization of Observability
The main results are local characterizations of observability and strong observability (or observability with unknown inputs) of A, C, and (A, B, C) and a generalized product rule for the differentiation of a product of matrices, where only one factor and the product itself are known to be differentiable.

Synthesis and Analysis of Nonlinear Control Systems Based on Transformations and Factorizations
Many real-world systems are inherently nonlinear by nature, hence it is of great benefit to develop control techniques for general nonlinear systems. In this thesis, we will investigate two specificExpand
