Abstract: The
turntable having multi-period disturbance torque is obtained by setting
up the dynamic unbalance model of three-axis turntable. The multi-period
disturbance torque is related to three-axis rotate speed of turntable
and influences localization precision, position precision and speed
precision of turntable. In order to attenuate system disturbance torque
of three-axis turntable, the method of multi-period finite-dimensional
repetitive control is proposed and proves to be a success in attenuating
the systematic error of turntable caused by multi-period disturbance.
The result of simulation shows that multi-period finite-dimensional
repetitive control can attenuate dynamic unbalance disturbance of
turntable system effectively.
