A New Consideration for Discrete-System Reduction via Impulse Response Gramian
نویسندگان
چکیده
Abstract: Recently a method of model reduction for discrete systems has been proposed in the literature based on a new impulse response Gramian. In this method, the system matrix Ar of a reduced model is computed by approximating the reduced-order impulse response Gramian. The remaining matrices br and cr are obtained so that various initial Markov parameters and time-moments of the original system are preserved in the reduced model. In this paper a different approach is presented based on the recursive relationship among the impulse response Gramians.

Properties of a Generalized Impulse Response Gramian with Application to Model Reduction
In identification or model reduction problems, an important task is the computation of the characteristic polynomial of the original or reduced-order system. Several literature have shown that the characteristic polynomial of a system can be extracted from the information generated by the impulse response data. For continuous systems, the Gram matrix [1,2] and the impulse response Gramian [3] a...
متن کاملNew Bases for Polynomial-Based Spaces
Since it is well-known that the Vandermonde matrix is ill-conditioned, while the interpolation itself is not unstable in function space, this paper surveys the choices of other new bases. These bases are data-dependent and are categorized into discretely l2-orthonormal and continuously L2-orthonormal bases. The first one construct a unitary Gramian matrix in the space l2(X) while the late...
متن کاملA Family of Variable Step-Size Normalized Subband Adaptive Filter Algorithms Using Statistics of System Impulse Response
This paper presents a new variable step-size normalized subband adaptive filter (VSS-NSAF) algorithm. The proposed algorithm uses the prior knowledge of the system impulse response statistics and the optimal step-size vector is obtained by minimizing the mean-square deviation(MSD). In comparison with NSAF, the VSS-NSAF algorithm has faster convergence speed and lower MSD. To reduce the computa...
متن کاملModel Reduction of Switched Systems Based on Switching Generalized Gramians
In this paper, a general method for model order reduction of discrete-time switched linear systems is presented. The proposed technique uses switching generalized gramians. It is shown that several classical reduction methods can be developed into the generalized gramian framework for the model reduction of linear systems and for the reduction of switched systems. Discrete-time balanced reducti...
متن کاملOn Model Reduction for Periodic Descriptor Systems Using Balanced Truncation
Linear periodic descriptor systems represent a broad class of time evolutionary processes in micro-electronics and circuit simulation in particular. In this paper we consider discrete-time linear periodic descriptor systems and study the concepts of periodic reachability and observability of the systems based on earlier ideas of Chu et al. [1]. We define reachability and observability Gramians ...
