A novel linear matrix inequality (LMI)-based criterion for the global asymptotic stability of two-dimensional (2-D) state-space digital filters described by the Roesser model employing various combinations of quantization and overflow nonlinearities is presented. The criterion is less restrictive than a previously reported criterion.

A recently reported criterion for the exponential stability and H ∞ performance of fixed-point digital filters with saturation arithmetic and external disturbance is reviewed. It is shown that there is a technical error in this criterion. A corrected version of the criterion is presented. Finally, a relaxed version of the criterion is made available.

This study discusses new criterion for the global asymptotic stability of two-dimensional digital filters described by the Fornasini-Marchesini second local state-space model under various combinations of quantisation and overflow non-linearities. The criterion is compared with a previously reported criterion.

This paper is concerned with the problem of global asymptotic stability of linear discrete-time systems with interval-like timevarying delay in the state. By utilizing the concept of delay partitioning, a new linear-matrix-inequality-(LMI-) based criterion for the global asymptotic stability of such systems is proposed. The proposed criterion does not involve any free weighting matrices but depends on both the size of delay and partition size. The developed approach is extended to address the problem of global asymptotic stability of state-delayed discrete-time systems with norm-bounded uncertainties. The proposed results are compared with several existing results.

This paper considers the problem of asymptotic stability of linear discrete-time systems with interval-like time-varying delay in the state. By using a delay partitioning-based Lyapunov functional, a new criterion for the asymptotic stability of such systems is proposed in terms of linear matrix inequalities LMIs . The proposed stability condition depends on both the size of delay and partition size. The presented approach is compared with previously reported approaches.

A linear matrix inequality (LMI) based criterion for the global asymptotic stability of discrete-time systems with multiple statedelays employing saturation nonlinearities is presented. Numerical examples highlighting the effectiveness of the proposed criterion are given.

Gyan Ganga, e-Gram, and Communication Information Center (CIC) are the ambitious project of government of India related to e-governance, which is the application of ICT in government functioning to bring in SMART governance. The paper describes about all three projects by individual SAP-LAP analysis and SAP-LAP analysis of all together. They use different technologies for the implementation and result will show the change in things due to this rapid change of technology.
