PURPOSE:To eliminate the personal difference of shortening and regulating a regulating time by automatically calculating a proportional constant to automatically decide and regulate the gain of an amplifier. CONSTITUTION:When starting an automatic regulation, a current command converter 12 is first switched to become a command iM* from a current setter 11. Calculating means 20 calculates a proportional gain Kp to be set to a proportional amplifier 7 from a target responding time (tau), the first detecting speed set value omegar1, the second detecting speed set value omegar2, accelerating time tacc measured by time counting means 18, and the value iM*. Gain setting means 21 sets the proportional gain Kp of the amplifier 7 on the basis of the calculated result. After the setting is finished, the converter 12 is switched so that the output of a control amplifier 1 becomes the input of a power converter 8 to substantially disconnect a block added for an automatic regulation, and a normal speed feedback control is performed. |
