TLDR
In this paper, a new output feedback variable structure power system stabilizer for a single-machine infinite-bus system is presented, where the stabilizer design is accomplished using extra dynamics in the form of a dynamic compensator.Abstract:
This paper presents a new output feedback variable structure power system stabilizer for a single-machine infinite-bus system The stabilizer design is accomplished using extra dynamics in the form of a dynamic compensator The method of equivalent control is used to describe the "augmented reduced order system" in the "sliding mode" Due to the reduction of order of the system in the sliding mode, the order of the compensator is usually less than the order of the compensator given by the Kimura-Davison formula A numerical example is worked out and the performance of the machine is investigated using different stabilizers to illustrate the effectiveness of the proposed designread more

A note on pole assignment in linear systems with incomplete state feedback
Edward J. Davison,R. Chatterjee +1 more
TL;DR: In this article, it was shown that if rank C = l, and if (A,B) are controllable, then a linear feedback of the output variables u = K*y, where K*is a constant matrix, can always be found, so that l eigenvalues of the closed-loop system matrix A + BK*C are arbitrarily close (but not necessarily equal) to l preassigned values.

A further result on the problem of pole assignment by output feedback
TL;DR: In this paper, a new result in the problem of pole assignment by gain output feedback is given, which states that arbitrary pole assignment is possible for almost all systems if n, r and m are the number of states, of inputs and of outputs, respectively, and ν and μ are the controllability index and the observability index of the system, respectively.
