CONTROL DEVICE FOR PERMANENT MAGNET SYNCHRONIZATION ELECTRIC MOTOR |
摘要 |
With an object of obtaining a control apparatus for a permanent magnet synchronous motor capable of performing highly accurate torque control not only during low-speed operation and medium-speed operation but also during high-speed operation without increasing a burden on a product CPU irrespective of whether the permanent magnet synchronous motor is an SPM motor or an IPM motor, the control apparatus includes a torque correction circuit (1, 2, or 3a) that generate a torque correction command T m *cmd from a current phase ² i of current correction commands (i d *cmd and i q *cmd) on a d-axis and a q-axis and a torque command T m * and supplies the torque correction command T m *cmd to a d/q-axis current command generator 9 instead of the torque command T m *.
