%0 Journal Article %T Nilpotency indices of state matrices and linear dependence on time of state variable of electrical circuits with state feedbacks %A Tadeusz Kaczorek %J Archives of Electrical Engineering %D 2010 %I %R 10.2478/s10171-010-0002-3 %X Electrical circuits with state-feedbacks are addressed. It is shown that by suitable choice of the gain matrices of state-feedbacks it is possible to obtain the closed-loop system matrices with nilpotency indices equal to two and their state variables are linear functions of time. The considerations are illustrated by linear electrical circuits. %K electrical circuits %K nilpotency indices %K state-feedback %U http://versita.metapress.com/content/k15h71720136n583/?p=ddbed828c7cb4bf0b093acd40fb336c5&pi=1
