Abstract: Sobolev type equations now constitute a vast area of nonclassical equations of mathematical physics. Those called nonclassical equations of mathematical physics, whose representation in the form of equations or systems of equations partial does not fit within one of the classical types (elliptic, parabolic or hyperbolic). In this paper we prove the existence of a unique optimal and hard control over solutions of Showalter–Sidorov problem for nonstationary operator-differential equations unresolved with respect to the time derivative. In this case, one of the operators in the equation is multiplied by a scalar function of the time-variable, besades stationary equation has a strong continuous degenerate resolving semigroup of operators. Apart from the introduction and bibliography article comprises two parts. The first part provides the necessary information regarding the theory of $p$-radial operators, the second contains the proof of main results of this article.

Keywords: optimal control, hard control, nonstationary Sobolev type equations, relatively radial case.
