One consider the optimal control problem for stationary equations of elastic waves diffraction on three-dimensional inclusion in unbounded homogeneous medium. The problem is to minimize $L^2$-deviation of pressure field in inclusion from the given. The control is the field source in the exterior medium. The solvability of problem is proved. The algorithm of is proposed.
