✦ Synopsis

In this paper, a new type generalized Lyapunov equation for discrete singular systems is proposed. Then it is applied to study problems such as pole clustering, controllability and observability for discrete singular systems. First, some necessary and su cient conditions for pole clustering are derived via the solution of this new type Lyapunov equation. Further, the relationship between the solution of the Lyapunov equation and structure properties of discrete singular systems will be investigated based on these results. Finally, a type of generalized Riccati equation is proposed and its solution is used to design state feedback law for discrete singular systems such that all the ΓΏnite poles of the closed-loop systems are clustered into a speciΓΏed disk.

In this paper, by using elementary analysis, we establish some new Lyapunov-type inequalities for nonlinear systems of difference equations when the coefficent Ξ² 2 (t) is not necessarily nonnegative valued and when the end points are not necessarily usual zeros, but rather, generalized zeros.

Four new stability theorems for general classes of retarded dynamical systems are established by using the Lyapunov function approach in this paper. A new technique is proposed for estimating the derivative of the Lyapunov function along the solution of a system at some specific instant. It is remar
