For a fixed tuple of square matrices X ={X_1,...,X_g} the set I(X) of all noncommutative polynomials p in X and Xâ such that p(X) = 0 is an ideal in the â-algebra of all polynomials. This article concerns such zeroes and their corresponding

The purpose of this paper is to present some preliminary results on the stability of the information state system. The information state system underlies the (infinite dimensional) dynamics of an H ∞ controller for a nonlinear system. Thus it is im

We present algorithms for solving general sup-norm minimization problems over spaces of analytic functions, such as those arising inH∞ control. We also give an analysis and some theory of these algorithms. Part of this is specific to analytic optim

In this paper, the practical existence of ideal MHD equilibria is investigated for various Tokamak designs. It is known from past experiment that, with increasing poloidal field-shaping coil distance, with increasing plasma elongation and with more s

We propose and analyse a method of estimating the poles near the unit circleT of a functionG whose values are given at a grid of points onT: we give an algorithm for performing this estimation and prove a convergence theorem. The method is to identif

The article concerns the H/sup /spl infin// multidisk problem which in other coordinates would be called an integral quadratic constraint (IQC) problem. We are given m/spl times/m matrix valued functions K/sup p/(e/sup i/spl theta//) for p=1,/spl mid
