Bounds on generalized structured singular values

[1992] Proceedings of the 31st IEEE Conference on Decision and Control, 2005
The authors present several bounds on the structured singular value (SSV). They first adopt a generalized notion of which is useful for problems where uncertainties are assumed to be bounded in an l/sub p/-induced matrix norm. Two different types of bounds, in terms of Perron root and interaction parameters, respectively, are given for the new SSV, and

Toward a structure singular value decomposition

26th IEEE Conference on Decision and Control, 1987
The concept of structured singular value was introduced by Doyle [1] as a tool for the analysis and synthesis of linear control systems with structured uncertainties. It is a key to the design of control systems under joint robustness and performance specifications and it nicely complements the H? approach to control system design [2,3]. It has already

An alternative characterization of the structured singular value

Proceedings of 1994 33rd IEEE Conference on Decision and Control, 2002
The size of the smallest, structured, destabilizing perturbation for a linear, time-invariant, system can be calculated via the structured singular value (/spl mu/). It can be bounded above by the solution of a linear matrix inequality (LMI). This paper gives an alternative characterization which is particularly suited to the case when the system (or ...

Computation of the real structured singular value

Guidance, Navigation and Control Conference, 1989
For a large class of linear time-invariant systems with real parametric perturbations, the coefficient vector of the characteristic polynomial is a multilinear function of the real parameter vector. Based on this multilinear mapping relationship together with the recent developments for wlvtmic wlvnomials and Darameter domain partitioning tkchnique ...

Upper bounds of structured singular values for mixed uncertainties

42nd IEEE International Conference on Decision and Control (IEEE Cat. No.03CH37475), 2004
Upper bounds of structured singular values for mixed uncertainties whose computations are efficient and reliable have been available. For uncertainties without real blocks and repeated complex scalar blocks, existing upper bounds are known to be quite tight.

Improved upper bounds for the mixed structured singular value

IEEE Transactions on Automatic Control, 1997
The authors consider the structured singular value \(\mu_K(M)\) of a complex \(n\times n\) matrix \(M\) with respect to some block structure \(K\) that defines the perturbation matrix \(\Delta\). \[ \mu_K(M)= \min_{\Delta\in\chi} \{\overline\sigma(\Delta),\text{ det}(I-\Delta M)= 0\}, \] \(\chi\) being a class of block diagonal matrices defined by \(K\)

Continuity properties of the real/complex structured singular value

IEEE Transactions on Automatic Control, 1993
Summary: The structured singular-value function \((\mu)\) is defined with respect to a given uncertainty set. This function is continuous if the uncertainties are allowed to be complex. However, if some uncertainties are required to be real, then it can be discontinuous.

Phase-sensitive structured singular value

1999
Given Γ ∈ C n ×n with Γ + Γ* ≥ 0, define the phase Φ(Γ) of Γ by $$\Phi \left( \Gamma \right) = {\cot ^{ - 1}}\left( {\sup \left\{ {b:\Gamma + \Gamma * - \frac{\beta }{j}\left( {\Gamma - \Gamma *} \right) \geqslant 0\forall \beta \in \left\{ { - b,\,b} \right\}} \right\}} \right).$$

A new upper bound for the real structured singular value

Proceedings of the 40th IEEE Conference on Decision and Control (Cat. No.01CH37228), 2002
A new, easily computable, upper bound on the real structured singular value /spl mu/ is derived under the assumption of a nonrepeated largest singular value. The condition under which real /spl mu/ is (strictly) less than the largest singular value is used to embed the structured uncertainty set in a larger related set.
