First Order Linear Systems
… <p>The objective of this project is to study systems of linear differential and difference equations. First, we compare two solution forms for the first order matrix differential equation Y'=AY+YB. The first form, due to Neudecker, utilizes the Kronecker products of matrices to convert an …

Regulation in Switched Bimodal Linear Systems
… control problems for a variety of engineering systems having smooth dynamics. In practice, one often encounters also non-smooth systems in various branches of science and engineering, such as for example mechanical systems subject to impact. Motivated by the read/write head flying height …

Optimal sensor placement for linear systems
… sensors. We compute the observer error, for the linear dynamical systems we consider, with the H2-norm of the observer error system. In this approach, we optimize both the subset of selected sensors and the observer gain matrix in parallel. The optimization problem is non-convex both in a …

Row Projection Methods for Linear Systems
Row projection (RP) methods for solving linear systems of equations are algorithms that require orthogonal projections onto the set of solutions of subsets of the equations. RP methods are categorized and their convergence properties summarized and extended. An implementation approach is presented …

Multidimensional Linear Systems and Robust Control
… and Noncommutative Multidimensional ($d$-D) Linear Systems Theory. The first part focuses on the development of the interpolation theory to solve the $H^{\infty}$ control problem for $d$-D linear systems. We first review the classical discrete-time 1D linear system in the operator theoretical …
