Sampling, infinite zeros and decoupling of linear systems
Ala~tmet--In order to understand more fully some of the trade-ot~ involved in using a sampled-data representation of a continuous-time system, the effects of time-sampling on the ability to achieve disturbance decoupling and input-output decoupling for linear systems are investigated. It is shown that disturbance decouplability is lost through sampling whereas row-by-row dynamic input-output de...
متن کاملInput and output decoupling zeros of linear periodic discrete-time systems
The notions of input and output decoupling zeros are extended to a linear periodic discretetime system. The ordered sets of structural indices are also analyzed for these notions and for the notions of invariant zero, transmission zero, eigenvalue and pole of such a system. For any non-zero zero, eigenvalue and pole, the corresponding ordered set of structural indices is timeinvariant. The inpu...
متن کاملDecoupling Zeros of Positive Discrete-Time Linear Sys-tems
The notions of decoupling zeros of positive discrete-time linear systems are introduced. The relationships between the decoupling zeros of standard and positive discrete-time linear systems are analyzed. It is shown that: 1) if the positive system has decoupling zeros then the corresponding standard system has also decoupling zeros, 2) the positive system may not have decoupling zeros when the ...
متن کاملZeros of SISO Infinite-Dimensional Systems
We give a definition of the zeros of an infinite-dimensional system with bounded control and observation operators B and C respectively. The zeros are defined in terms of the spectrum of an operator on an invariant subspace. These zeros are shown to be exactly the invariant zeros of the system. For the case of SISO systems, where also the range of B is not in the kernel of C, we show that this ...
