1. A control apparatus comprising:
one or more hardware processors configured to
acquire, for each of elements, pieces of input data representing a first physical field of a corresponding one of the elements at a first time point, the elements being obtained by discretization of an analysis area as an object to be controlled wherein
the object to be controlled is an object performing self-excited oscillation or self-excited rotation for generating an excitation force;
calculate, for each of the elements, a second physical field of a corresponding one of the elements at a second time point after the first time point, the second physical field being calculated based on a value of an energy functional representing energy of the corresponding one of the elements, the value of the energy functional being obtained by inputting the pieces of input data into an estimation model; and
control the object to be controlled such that control quantity based on the second physical field becomes a target value.
