PURPOSE: To obtain a method for controlling the speed of a motor using a speed controller in which the productivity is enhanced while avoiding degradation of quality by employing such method as the achieved speed follows up a reference speed even when the response of a speed control system can not be ensured sufficiently. CONSTITUTION: When the transfer functions are known for a speed controller 3, a current controller 4, and a motor 5, a speed compensation circuit 1 (GCMP (s)) can be derived where the transfer function from a speed reference (SREF) to a speed achievement (SFBK) is 1. Output from the speed compensation circuit 1 is added to an essential speed reference and fed to the speed controller 3 thus improving the target value response to a speed command regardless of the transfer function of control system. |
