Robust control design of power system stabilizers using multivariable frequency domain techniques
TLDR
In this article, structured singular value optimization techniques are used to design robust power system stabilizers (PSS) for a single-machine and a two-machine system with varying operating conditions.Abstract:
H∞ and structured singular value optimization techniques are used to design robust power system stabilizers (PSS) for a single-machine and a two-machine system with varying operating conditions. Realistic uncertainty models to represent the possible operating conditions as perturbations from a nominal operating condition are developed. System experience is used to select weighting functions to provide adequate damping and shape the controller frequency response. Computer simulations show that the PSS designed using the proposed technique provides improved damping compared to a conventional PSS.read more

Characterization and efficient computation of the structured singular value
M. Fan,André L. Tits +1 more
TL;DR: It is shown that the structured singular value can be obtained as the solution of several smooth optimization problems, leading to a fast algorithm that always yields the structured plural value for block structures of size no larger than 3, and often does for blockstructures of larger size.

A pole-placement design approach for systems with multiple operating conditions
TL;DR: In this paper, the authors proposed a design procedure based on state-space pole-placement techniques for systems with multiple operating conditions, which is the so-called simultaneous poleplacement problem, and the design condition is formulated in terms of the rank condition of a multimode controllability matrix.
