✦ Synopsis

A class of multi-dimensional damped distributed parameter systems with pointwise timedelayed displacement is considered. The linear systems with delayed control action are transformed into equivalent systems without delays. It is shown that the feedback gain control exists and asymptotically stabilizes the closed-loop modal system. An analysis of the e!ectiveness of using pointwise time-delayed displacement under these condition is studied. Speci"c numerical results are given for a structurally damped beam for various parameters when the pointwise delayed displacement feedback control is applied.

This paper presents the stability analysis of linear, damped SDOF vibration control systems with two time delays, one in the displacement feedback and the other in the velocity feedback. First, a sufficient and necessary algebraic criterion is proved to check the system stability independent of time

## Abstract The suboptimal control policy obtained from series expansion of time‐delay terms is useful when the delays are small. The second method involving direct search on the constant gain matrix is applicable even for large delays. Both of these proposed methods are computationally simple and

In this paper, we solve the disturbance-rejection and tracking problem for linear multivariable discrete-time systems with time-delayed controlled inputs. A set of necessary and sufficient conditions under which the proposed problem is controllable is defined. Also, the nilpotency properties of such
