摘要：We consider control properties for second-order hyperbolic systems in anisotropic cases with variable coefficient matrices in a bounded domain in R-n with C-2-boundary. Assuming that the coefficient matrices satisfy suitable conditions, we establish observability inequalities for hyperbolic systems in anisotropic cases. Then, using the Hilbert uniqueness method, we deduce the exact controllability of the corresponding control problem for hyperbolic systems in anisotropic cases. The same results for linear elastodynamic systems in inhomogeneous and anisotropic media are provided to illustrate the application of the results.
