This paper deals with the development of square-root balanced truncation algorithm to reduce the order of power system models along with the preservation of interaction relations between study area and the external area. Further, the balanced approach is extended with the singular perturbation approximation technique. For illustration of developed algorithms, external area model of a four machine...
In this paper a square-root balanced approach based frequency weighted optimal Hankel norm model reduction algorithm is developed as an extension of [21] and [25]. The proposed algorithm generates stable reduced order models with single and double-sided weighting functions. A numerical example is included and the results are compared with the existing techniques as a validation of developed algorithm.
Offers on e-commerce websites have been mostly a decision made by companies for advertising or clearing stocks. KAAL algorithm was used on sample transaction data to generate frequent itemsets. These frequent itemsets will give an idea of offers to be made on purchase of base items. With advent of internet, the amount of data being generated by business processes is growing exponentially. This paper...
In this paper a new frequency weighted model reduction algorithm is proposed which is based on a combination of Wang et al's technique [14] and balanced singular perturbation approximation. The proposed algorithm results stable reduced order models with both single sided and double-sided weightings. A numerical example is considered to validate the proposed algorithm and the comparison with other...
This paper presents a generalized frequency weighted optimal Hankel norm model reduction (GFWOHNMR) technique. The proposed algorithm is an extension of approach discussed in [9] and results stable reduced order models with both single sided and double sided weightings. A numerical example is considered to validate the proposed algorithm.
The present work deals with the problem of frequency weighted controller reduction using optimal Hankel norm approximation. The advanced controller designs methods like LQG/LTR or H∞ based synthesis methods leads to controllers of order comparable to the plant and sometimes unstable controller whereas lower order controller should be sought out to keep the closed-loop stability and system performance...
