Abstract
The present disclosure relates to a motor control system including: a motor control device, including a semiconductor integrated circuit having a memory and forming a control loop for a motor so as to control a drive of the motor; and an external debug device, externally connected to the motor control device and accessible to the memory in the motor control device. The external debug device includes a disturbance signal superimposer and a frequency characteristics deriver. The interference signal superimposer generates a disturbance signal for the control loop and superimposes the disturbance signal on a signal generated in the control loop. The frequency characteristics deriver derives frequency characteristics of the control loop based on the signal generated in the control loop by superimposition.
