CURRENT COMMAND TABLE AUTOMATIC GENERATION SYSTEM AND CURRENT COMMAND TABLE AUTOMATIC GENERATION METHOD FOR EMBEDDED MAGNET SYNCHRONOUS MOTOR

摘要

PROBLEM TO BE SOLVED: To provide a current command table automatic generation system capable of automatically generating d-axis and q-axis current command values with high accuracy on the basis of an actual value.SOLUTION: A system for automatically generating a current command table for converting a torque command to be given to an inverter 40 for performing variable speed control of an embedded magnet synchronous motor 10 into d-axis and q-axis current command values includes a current command table automatic generation device 30 which causes a load servo device 20 to perform speed control, performs torque feedback control so as to cause a torque detection value to coincide with a torque command value set at one operation point to generate a q-axis current command value, retrieves and generates a d-axis current command value for satisfying desired performance on the basis of various information of the current command table automatic generation system in a state undergoing the torque feedback control, and associates the d-axis current command value and the q-axis current command value generated about the entire operation points with a revolution speed and the torque, respectively to make a table.SELECTED DRAWING: Figure 1
