Abstract:
A control system comprising a feedback controller  1  for determining an operation amount u in a control-implemented system based on a command value r*, a detection value y of the control-implemented system and phase information θ for die control-implemented system, wherein the feedback controller  1  has a periodic disturbance suppression controller  4  for outputting a periodic disturbance compensation signal r pd * based on the detection value y mid the phase information θ; and a resonance/disturbance suppression controller  3  for calculating the operation amount u based on the detection value y and a corrected command value r obtained by adding the periodic disturbance compensation signal r pd * to the command value r*. The periodic disturbance suppression controller  4  uses a generalized periodic disturbance observer. In the control system, resonance, non-periodic disturbances and periodic disturbances are all suppressed in order to raise the system control performance.

Claim (Index 1):
A control system comprising a feedback controller for determining an operation amount in a control-implemented system based on a command value, a detection value of the control-implemented system and phase information for the control-implemented system, wherein\n the feedback controller has: a periodic disturbance suppression controller for outputting a periodic disturbance compensation signal based on the detection value and the phase information; and a resonance/disturbance suppression controller for calculating the operation amount based on the detection value and a corrected command value obtained by adding the periodic disturbance compensation signal to the command value; and the periodic disturbance suppression controller uses a generalized periodic disturbance observer, and wherein the resonance/disturbance suppression controller has: a \u03bc-synthesis controller for adding an output obtained by subjecting the command value to transfer properties of the \u03bc-synthesis controller, from the command value to the operation amount, to an output obtained by subjecting the detection value to the transfer properties of the \u03bc-synthesis controller, from the detection value to the operation amount, and outputting the operation amount; and the periodic disturbance suppression controller has: a frequency component extractor for extracting a frequency component from the detection value by using an nth-order rotational phase obtained by multiplying a suppression target order number n with the phase information, and outputting an nth-order frequency component vector of periodic disturbances converted to d n q n  rotating coordinates; a speed converter for calculating an nth-order rotational frequency by differentiating the nth-order rotational phase; an inverse model multiplication unit for determining an nth-order frequency component vector of an operation amount estimate value by multiplying, with the nth-order frequency component vector of the periodic disturbances, an inverse model to which a single frequency vector synchronized with the nth-order rotational frequency is applied; a first subtractor for subtracting, from the nth-order frequency component vector of the operation amount estimate value, a value obtained by passing an nth-order frequency component vector of a periodic disturbance compensation value through a low-pass filter, and outputting an nth-order frequency component vector of a periodic disturbance estimate value; a second subtractor for subtracting, from an nth-order frequency component vector of a periodic disturbance command value, the nth-order frequency component vector of the periodic disturbance estimate value, and outputting the nth-order frequency component vector of the periodic disturbance compensation value; and a compensation signal synthesis unit for restoring the nth-order frequency component vector of the periodic disturbance compensation value from the d n q n  rotating coordinate system synchronized with the periodic disturbances to a time waveform based on the nth-order rotational phase, and outputting the periodic disturbance compensation signal.
