Controllability of singular linear systems by Legendre wavelets [PDF]

open access: yesInternational Journal of Information and Communication Technology, 2014
We propose a new method to design an observer and control the linear singular systems described by Legendre wavelets. The idea of the proposed approach is based on solving the generalized Sylvester equations. An example is also given to illustrate the procedure.
