. The infinity norm of a function f exists iff every p -norm exists with ∥f∥∞=limn→∞∥f∥n . In case of a finite dimensional vector (x1,x2,…,xk) wherein we assume WLOG that 0≤x1≤x2≤…≤xk<∞ , we have xk≤(xkn)1/n≤(x1n+x2n+…+xkn)1/n≤k1/nxk.(1) Th...
In this paper we propose an efficient computation approach to minimize the H-infinity-norm of a transfer-function matrix depending affinely on a set of free parameters. The minimization problem, formulated as a semi-infinite convex programming problem, is solved via a relaxation approach over a ...
It is well known that in the finite dimensional case H∞ norm of a system is computed using the connection between the singular values of the transfer function and the imaginary axis eigenvalues of an Hamiltonian matrix. We show a similar connection between the singular values of a transfer ...

In this paper, a new method based on minimum infinity-norm joint velocity solutions for a redundant manipulator is proposed to lead it pass through singularities without excessive joint velocities. The infinity-norm is used to overcome the limitations of the minimum 2-norm solutions. In order to...
Based on the H-inflnity control theory, we consider an aeroelastic system a multiple-input and multiple-output (MIMO) system, and derive its transfer function matrix. The H-infinity-norm of this transfer matrix will approach to infinity near the critical flutter point. Using this unique ...
If realistic multivariable performance objectives are to be represented by a single MIMO ∥·∥∞ objective on a closed-loop transfer function, additional scalings are necessary. Because many different objectives are being lumped into one matrix and the associated cost is the norm of the matrix, ...
-norm of is Strictly speaking, -norm is not actually a norm. It is a cardinality function which has its definition in the form of -norm, though many people call it a norm. It is a bit tricky to work with because there is a presence of zeroth-power and zeroth-root in it. Obviously...
The type(x, pos_infinity) function returns true if x is a positive real_infinity. • The type(x, neg_infinity) function returns true if x is a negative real_infinity. • The type(x, SymbolicInfinity) function returns true if x is either 1. of type infinity 2. a product with...
Suppose in addition that S is a non-compact locally compact Hausdorff space. The space C0(S) of all those continuous complex-valued functions on S which vanish at infinity is a norm-closed subalgebra of lcℂ(S), and hence a commutative Banach algebra in its own right under the supremum...
