A numerical solution for the simultaneous disturbance decoupling and row-by-row decoupling problem

Disturbance rejection and row-by-row decoupling for linear delay systems of neutral type

where x(t) ∈ IRn is the state, u(t) ∈ IRp the input, d(t) ∈ IRq is a disturbance and y(t) ∈ IRm the output. The matrices A0, A1, A−1, B0, C0 and D0 are of suitable dimensions. In this paper we assume that matrices B0 and C0 are of full rank. There are more general forms of delay systems of neutral type: with several delays, with distributed delays... Our considerations may be formulated for sys...

A Matrix Pencil Approach to the Row by Row Decoupling Problem for Descriptor Systems

The row by row decoupling problem (RRDP) for descriptor systems is considered using proportional state feedback and input transformation. Necessary and sufficient conditions for the solvability of the RRDP are provided. These solvability conditions can be readily verified. A constructive solution to the RRDP is given so that the desired feedback and input transformation matrices can be obtained...

Weak structure at infinity and row-by-row decoupling for linear delay systems

Disturbance decoupling by measurement feedback

The paper addresses the disturbance decoupling problem for MIMO discretetime nonlinear systems. A sufficient conditions are derived to solve the problem by dynamic measurement feedback, i.e. the feedback that depends on measurable outputs only. The solution to the disturbance decoupling problem, described in this paper, is based on the input-output linearization, which is used to linearize cert...

برد عددی ماتریس مربعی a را با w(a) نشان داده و به این صورت تعریف می کنیم w(a)={x8ax:x ?s1} ، که در آن s1 گوی واحد است. در سال 2009، راسل کاردن مساله برد عددی معکوس را به این صورت مطرح کرده است : برای نقطه z?w(a)، بردار x?s1 را به گونه ای می یابیم که z=x*ax، در این پایان نامه ، الگوریتمی برای حل مساله برد عددی معکوس ارانه می دهیم.
