摘要： An instruction value generation device comprises: an instruction response calculation unit (102) that predictively calculates, on the basis of a model on a calculator, a response path along which a control target is actually operated when an instruction path is given; a target path determination unit (104) that determines a target path along which the control target is operated; an instruction path generation unit (105) that regenerates a temporary instruction path on the basis of the target path and a temporary instruction response path obtained when the temporary instruction path is given to the instruction response calculation unit (102); a convergence-determination-condition determination unit (103) that determines a convergence determination condition used in a determination processing of determining whether an error between the temporary instruction response path and the target path is converged; and a path comparison unit that performs the determination processing on the basis of the convergence determination condition. The regeneration of the temporary instruction path and the calculation of the temporary instruction response path are repeated until the path comparison unit determines that the convergence determination condition is met, and the temporary instruction path is output to a control device (700) controlling the control target, as the instruction path for operating the control target when the path comparison unit determines that the convergence determination condition is met.

摘要： A numerical control device that controls a servomotor on the basis of a machining program. The machining program determines whether or not to perform correction on reversal of a moving direction of a mechanical system driven in a movement axis direction by the servomotor. This is done on the basis of the machining program including an instruction that causes the reversal of the moving direction of the mechanical system and another instruction to be executed later than the instruction.
