Method for controlling velocity of rotary motor and apparatus therefor |
摘要 |
A velocity method for a rotary motor and an apparatus adopting the same, estimates and corrects a disturbance applied to the rotary motor to improve a velocity control characteristic, in which the disturbance is expressed as a function of an angular velocity and an angular position via a simple calculation process. The velocity control apparatus includes a learning compensator (27) for receiving a velocity command, angular position information and the output from a velocity controller (21) and correcting an effect of the disturbance which is expressed as a function of the angular velocity and the angular position, in addition to a general velocity control loop of a rotary motor composed of a velocity controller, a current controller, a motor and a velocity measuring unit. The learning compensator (27) stores one period of the output of the velocity controller (21) at the stable state of the velocity control loop and obtains a correction value using the stored value and the previous output value. Thus, the correction value obtained in the learning compensator (27) is stored in advance and a velocity control is performed using the stored value, to enable a simple and efficient velocity control. <IMAGE> |
