Title:
MOTOR CONTROL APPARATUS
Document Type and Number:
WIPO Patent Application WO/2011/145476
Kind Code:
A1
Abstract:
Provided is a motor control apparatus, wherein over-shooting of pressure can be inhibited from happening, and follow-up capability of a dynamic physical-quantity of a mechanical load for acting upon an object to be pressurized, with respect to a physical-quantity command value, can be improved. Driving of a motor (2) is controlled by a motor control apparatus main-body (10). The motor control apparatus main-body (10) comprises a pressure command signal generating unit (11), a pressure control unit (12), a velocity control unit (13), and a current control unit (14). The pressure-command signal generating unit (11) generates a pressure command value so as to make a value the result of differentiating the pressure command value not more than the product of the elastic constant (K) of the object to be pressurized and the maximum motor velocity (Vmax). The pressure control unit (12) executes a pressure control calculation to calculate a motor-velocity command value that is in accordance with the deviation between the pressure command value and the actual pressure value, and generates a motor-velocity command signal (12a) that is the signal of the motor-velocity command value.
