Simulation device, simulation method, and simulation program

A simulation method, simulating a control system having a control object comprising a motor and a motor control device controlling the motor, wherein the simulation method comprises:

• calculating a time response of a predetermined device-side configuration comprising the control object to a predetermined input value, by convolution processing using impulse response information for calculation which is information on an impulse response relating to the predetermined device-side configuration and the predetermined input value;
• and
• calculating a response of the simulation system to a command value input to the simulation system, by using the time response of the predetermined device-side configuration calculated in the calculation step by the convolution processing, based on a simulation system comprising a predetermined feedback system having, as a forward element, at least a predetermined control block structure corresponding to the predetermined device-side configuration.

A simulation program stored on a non-transitory recording medium, causing a simulation device simulating a control system having a control object comprising a motor and a motor control device controlling the motor to execute:

• a step of calculating a time response of a predetermined device-side configuration comprising the control object to a predetermined input value, by convolution processing using impulse response information for calculation which is information on an impulse response relating to the predetermined device-side configuration and the predetermined input value;
• and
• a step of calculating a response of the simulation system to a command value input to the simulation system, by using the time response of the predetermined device-side configuration calculated in the calculation step by the convolution processing, based on a simulation system comprising a predetermined feedback system having, as a forward element, at least a predetermined control block structure corresponding to the predetermined device-side configuration.
