<p>PURPOSE:To enable an actual torque command value to be controlled according to an accelerator stepping-on degree, by correcting a torque command value based on inertia energy computed from the acceleration and the motor inertia value of motor rotationalfrequency. CONSTITUTION:The rotational frequency theta1 of a motor is detected by a rotational frequency detector, and its value is differentiated by a differentiating circuit, and acceleration theta1'' is found. Then, from J1 corresponding to the inertia value of the motor and the acceleration theta1'', the inertia energy J1.theta1'' of the motor is found. Besides, the inertia energy J1.theta1'' is added to a torque command value T' according to an accelerator stepping-on degree, to find an actual torque command value T, and is transmitted to an inverter controller for controlling the torque of the motor. As a result, the accelerator stepping-on degree can be controlled to be equal to driving shaft output torque.</p> |
