Decentralized pole placement using polynomial matrix fractions
… field of decentralized control is the arbitrary pole placement using output feedback. The feasibility of this problem depends solely on the identification of the decentralized fixed modes. As a matter of fact, if the system is free of fixed modes, then by increasing the controller’s order, any …

Optimal actuation in active vibration control using pole-placement
… vector, or input vector, to accomplish the pole placement, finding the optimal location of actuators and their relative gain so that the control effort is minimized. The problem was of finding the optimal input vector of unit norm that minimizes the norm of the control gain vector. The …

Pole-placement with minimum effort for linear multivariable systems
… is concerned with the problem of the exact pole-placement by minimum control effort using state and output feedback for linear multivariable systems. The novelty of the design lies in obtaining a direct transformation of the system matrices into a modified controllable canonical form. Two …

A design procedure for model reference adaptive control
… robustness of four distinct control approaches: pole placement; the command generator tracker (CGT) approach to model reference control; model reference adaptive control (MRAC); and MRAC using a fixed feedback gain. We use a second order, single-input single-output (SISO) plant to examine the …

The application of self-tuning control to rolling mill systems.
… mill is considered. This is a new application of pole-placement self-tuning control and no comparable examples have been found in the literature. Initially, an existing ACSL model was investigated and a simpler version, suitable for online use was developed. A simpler MATLAB model of the system …

The internal performance of iterative feedback tuning
… (IFT) may produce a controller that cancels the poles of the process and as a result can give a closed loop that has poor internal performance. The disadvantage of this is that the closed loop will have poor input disturbance rejection. A solution for ensuring that IFT does not have poor internal …

Pseudo-linear indentification and its application to adaptive control
… algorithm is proposed which utilizes pole–placement state variable feedback via Ackermann's formula. The capabilities of this adaptive control scheme are demonstrated by application to a full-order nonlinear aircraft simulation model where significant improvement is shown over …

Multivariable Adaptive Control
… of adaptive control is discussed extensively. A pole-placement problem and a model-matching problem are formulated and interpreted in terms of model reference control. The problem is solved via a discussion on system invariants of multivariable systems as presented by Pernebo. The attention is …

A proposed methodology for the control of a semi-robotic convoy
… controlled in one degree-of-freedom (DOF) using pole-placement, state-feedback control theory. The analysis shows this to be an unacceptable method of control due to the steady-state error. The 1 DOF model is then controlled with series compensation. Simulations verify that the steady-state error …

Vibration Suppression using Orthogonal Eigenstructure Control
… controller designer may also be required to do pole placement. Considering the fact that there are no one-to-one relationships between the elements of the closed-loop eigenvectors of a model and the states of the system, this effort could be inefficient for many practical systems. Moreover, for …
