โœฆ Synopsis

Zntroduction

In this paper we compare the behavior of a multivariable feedback system with that of a "comparison" open-loop system. We view the "plant" P, the "precompensator" G and the "feedback" F as operators taking vectorvalued inputs into vector-valued outputs ; P, will denote the normal value of the plant operator. The plant will undergo some changes from P, to P = P,+ AP where no size requirements are imposed on AP and from P, to P, +6P, for "small" changes. Our object is to compare the feedbacksystem output yC and the "comparison-open-loop system" output y0 as the plant changes.

A practical method is presented for the analysis of limit cycles in multivariable feedback control systems having separable nonlinear elements. The limit cycles are found by use of a criterion generated by the stability-equation method. Numerical examples are given and compared to other methods in t

In this paper, the stabilization problem of two classes of nonlinear singularly perturbed systems via dynamic output feedback is investigated. First, we consider the nonlinear singularly perturbed systems in which the nonlinearities are continuously differentiable. The theoretical result demonstrate

In this paper tradeoffs in multivariable sensitivity reduction are developed for a new Directional Sensitivity Function (DSF). The directions considered belong to direction modules of the nonminimum phase zeros (NMP) and unstable poles of the transfer matrices. The well known Bode Integral is extend
