Optimal Reduction of Multivariate Dirac Mixture Densities [PDF]
arXiv, 2014 This paper is concerned with the optimal approximation of a given multivariate Dirac mixture, i.e., a density comprising weighted Dirac distributions on a continuous domain, by an equally weighted Dirac mixture with a reduced number of components. The parameters of the approximating density are calculated by minimizing a smooth global distance measure,

Multivariable analytic interpolation with complexity constraints: A modified Riccati approach [PDF]
arXiv, 2019 Analytic interpolation problems with rationality and derivative constraints occur in many applications in systems and control. In this paper we present a new method for the multivariable case, which generalizes our previous results on the scalar case. This turns out to be quite nontrivial, as it poses many new problems. A basic step in the procedure is

Synthesis of restricted inertial controls for systems with multivariate control
Journal of Mathematical Analysis and Applications, 2002 AbstractThe local positional synthesis problem for the control system ẋ=f(x,u), x∈Rn, u∈Rr, under preassigned restrictions ‖u(k)(x)‖⩽dk on derivatives of control with respect to the closed system up to given order, 0⩽k⩽l, is considered. The controllability function method is the basis of the investigation.

On Robust Stability of Multivariable Interval Control Systems [PDF]
arXiv, 2005 This paper studies robustness of MIMO control systems with parametric uncertainties, and establishes a lower dimensional robust stability criterion. For control systems with interval transfer matrices, we identify the minimal testing set whose stability can guarantee the stability of the entire uncertain set.
