Abstract
A control system comprising a feedback controllerfor 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 the control-implemented system, wherein the feedback controllerhas a periodic disturbance suppression controllerfor outputting a periodic disturbance compensation signal r* based on the detection value y and the phase information θ; and a resonance/disturbance suppression controllerfor 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* to the command value r*. The periodic disturbance suppression controlleruses 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.
