The paper studies the reliability (sensor and actuator failures) of the asymptotic disturbance rejection problem for linear time invariant systems using the factorization approach, assuming that not all loops fail simultaneously and that sensor and a

This paper studies the reliability with sensor failures of the asymptotic tracking problem for linear time invariant systems using the factorization approach. The plant is two-output and the compensator is two-degree-of-freedom. Necessary and suffici

The paper studies the invariance of infinite input-decoupling, output-decoupling, input-output-decoupling zeros, infinite zeros of the transfer function matrix and infinite system zeros under constant output and state feedback.

The paper studies the robustness of the servomechanism in the transfer function matrix set-up. First the minimum-order internal model is considered, then the redundant one, with some or all of the plant's parameters arbitrarily perturbed.

Rosenbrock's definition of system zeros is extended for zeros at infinity. Its relationship with transfer function zeros and decoupling zeros is established.

The paper compares the unity feedback with the non-unity feedback servo problem from the point of view of sensitivity and the minimum order of the realization. It is proved that the non-unity feedback solution has smaller sensitivity ‘on the band o

Simple, necessary and sufficient conditions for system equivalence at infinity and strong system equivalence of systems in the form (T(s), B, C, D) are established. A necessary condition for system equivalence at infinity of systems in the general fo

The paper studies the tracking problem of linear multivariable systems using the fractional representation approach introduced by Desoer et al. (1980). This method applies not only to lumped-parameters systems, but also to some classes of distributed

The paper solves the asymptotic tracking/ disturbance rejection problem for feedback systems with two-input, two-output plant and compensator using the factorization recently unveiled by Nett [3] and Desoer and Gunde?[4].
