Easily Testable Necessary and Sufficient Algebraic Criteria for Delay-independent Stability of a Class of Neutral Differential Systems
Ping Wei, Qiang Guan, Wensheng Yu +1
This paper analyzes the eigenvalue distribution of neutral differential systems and the corresponding difference systems, and establishes the relationship between the eigenvalue di…
Solution to the Generalized Champagne Problem on Simultaneous Stabilization of Linear Systems
Qiang Guan, Long Wang, Bican Xia +3
The well-known "Generalized Champagne Problem" on simultaneous stabilization of linear systems is solved by using complex analysis \cite{A73,C78,G69,N52,R87} and Blondel's techniqu…
Edge Theorem for Multivariable Systems
Long Wang
This paper studies robustness of multivariable systems with parametric uncertainties, and establishes a multivariable version of Edge Theorem. An illustrative example is presented.
H-infinity Performance of Interval Systems
Long Wang
In this paper, we study performance of interval systems. We prove that, for an interval system, the maximal norm of its sensitivity function is achieved a…
Robust Strictly Positive Real Synthesis for Polynomial Families of Arbitrary Order
Long Wang
For any two - order polynomials and the Hurwitz stability of their convex combination is necessary and sufficient for the existence of a polynomial suc…
Improved Results on Robust Stability of Multivariable Interval Control Systems
Long Wang
For interval polynomial matrices, we identify the minimal testing set, whose stability can guarantee that of the whole uncertain set. Our results improve the conclusions given by K…
