This paper proposes a new methodology for subspace identification of linear time-periodic (LTP) systems with periodic inputs. method overcomes the issues related to computation frequency response LTP by utilizing time-lifted system time-invariant structure instead. The is estimated an ensemble input-output data allows frequency-domain technique be extended systems. time-aliased impulse can then...

The problem of pole assignment, also known as an eigenvalue assignment, in linear discrete-time periodic systems in discs was solved by a novel method which employs elementary similarity operations. The former methods tried to assign the points inside the unit circle while preserving the stability of the discrete time periodic system. Nevertheless, now we can obtain the location of eigenvalues ...
