Eigenstructure assignment by output feedback

International Journal of Control, 1991
This paper looks at the problem of eigenstructure assignment using the system outputs. The algorithm developed is a single pass solution based on the singular value decomposition used to assess rank deficiency. The technique uses metrics to assess the time response, actuator movement and output decoupling of the eigenstructure problem.

Eigenstructure assignment in linear descriptor systems

IEEE Transactions on Automatic Control, 1995
Summary: Given a linear controllable system \(E\dot x= Fx+ Gu\), we study the limits of linear proportional feedback \(u= Kx+ v\) in assigning a desired finite and infinite eigenstructure of the closed-loop system \(E\dot x= (F+ GK)x+ Gv\). The closed-loop system is not restricted to be regular; its rank makes part of the specifications.

Eigenstructure assignment characterisation

2011
In this chapter, the eigenstructure synthesis using state variable feedback has been analysed. It is shown that the solution scheme is simple and just involves solving a set of linear equations to synthesise each eigenvector for a specified eigenvalue.

Integrated approach to observer eigenstructure assignment

IEE Proceedings - Control Theory and Applications, 2000
An integrated approach to eigenstructure assignment is used to provide a simple unconstrained algorithm for full-state-observer left-eigenstructure assignment. The integrated approach enables the left-eigenstructure, assignable with multiple eigenvalues, to be readily identified. The approach is developed to provide a simple unconstrained algorithm for

Robust eigenstructure assignment

2011
The design of feedback systems based on a 'mathematical model' of the plant should be insensitive to uncertainty associated with the parameters of the model. This is required since the system model parameters, in most cases, are only a best estimate of the real plant.

Optimisation approach to robust eigenstructure assignment

IEE Proceedings - Control Theory and Applications, 1999
A systematic optimisation approach to robust eigenstructure assignment for control systems with output feedback is presented. The proposed scheme assigns the maximum allowable number of closed-loop eigenvalues to desired locations, and determines the corresponding closed-loop eigenvectors as close to desired ones as possible.

Eigenstructure assignment technique for manipulator control

Conference Proceedings., IEEE International Conference on Systems, Man and Cybernetics, 2003
A control scheme based on a procedure suggested by M. Vukobratovic and N. Kircarski (1983) is used to design the control algorithm for a two-link robot arm. Simulation results show that eigenstructure assignment with feedforward torques can produce acceptable performance for such an arm.

Eigenstructure assignment using output feedback

IEEE Transactions on Aerospace and Electronic Systems, 1994
An eigenspace, achievable by gain output feedback, is proposed by Andry et al. (1983). One example contradicting the above conclusion is given by Kang and Lee (1992). The contradiction is due to the limitation of the result presented by Andry. This note derives the complete specification of the eigenspace which can be achieved by gain output feedback. >

An addendum to output feedback eigenstructure assignment: retro-assignment

International Journal of Control, 2004
This addendum paper presents additional material on an output feedback eigenstructure assignment approach derived in Clarke et al. (2003). There, a two-stage process is followed in which a subset of the desired eigenvectors is assigned in the first stage, followed by a dual set in the second stage.
