Abstract
A numeric control apparatus for machine tools having a moveable member which is operated by a servomotor, including a controlled system, where the controlled system includes a servomotor and a moveable member, and a model of the controlled system, having a system parameter. The numeric control apparatus also includes a command generator for generating a command value, a reference input value generating controller for transmitting a reference input value to the controlled system and to the model, in response to receiving the command value, and an analyzing section for storing a measured output of the controlled system and a measured output of the model. The numeric control apparatus further includes a servo controller for transmitting a simulation current to the model, in response to receiving the command value, where the servo controller includes design parameters, and a user interface section for receiving an operator input, where the operator input includes the reference input value, the simulation current, the design parameters, and the system parameter of the model.
