✦ Synopsis

This review article consists of two parts. The first part concerns the admissibility of four contributions characteristic for Biot's model of poroelastic materials: coupling of partial stresses, presence of relative accelerations in equations of motion, dependence of permeability on frequency and changes of porosity. The second part is devoted to the demonstration of those contributions in the analysis of acoustic waves. Propagation of fronts, monochromatic waves and surface waves are considered.

The deterministic controller of Leilmann and/or variablestructure controllers have been used as the robust control strategy which assures stability for linear systems having uncertainties caused by parameter variations and disturbances. For both control strategies, however, chattering may be genera
