Title:
TORQUE COMMAND GENERATION DEVICE
Document Type and Number:
Japanese Patent JP2014215253
Kind Code:
A
Abstract:
PROBLEM TO BE SOLVED: To provide a torque command generation device for generating a motor generation torque command to maximize an exciting force while securing a necessary acceleration or the like within a limited range of motor torque.SOLUTION: A torque command generation device 6 includes: a maximum torque calculation part 633 for calculating the maximum torque value corresponding to the value of a motor generation torque command signal in accordance with motor rotational frequency; a DC component limiter 635 for calculating the value of a DC signal; a surplus amplitude calculation part 637 for calculating a surplus amplitude by subtracting the maximum torque value from the sum of the DC component value calculated by the DC component limiter 635 and an excitation amplitude input from the outside; a sine wave transmitter 639 for generating the sine wave of amplitude obtained by subtracting the surplus amplitude from basic amplitude; and an addition part 640 for calculating the value of the motor generation torque command signal by adding the DC component value and the value of the sine wave.
