Abstract: PURPOSE:To reduce the control deviation and to improve the performance of a controller by turning the control deviation, i.e., the difference between the control target value and a variable to be controlled into a manipulated variable of a control subject via a stabilized compensator and a secondary compensator. CONSTITUTION:When the control target value (r) is received, the deviation (e) between the value (r) and a variable (y) to be controlled is inputted to a secondary compensator 2. Then a manipulated variable (u) is outputted and inputted to a control subject 1 to which the disturbance (d) is already inputted. The variable (y) is outputted based on the variable (u) and the disturbance (d) and fed back. The compensator 2 increases the open loop gain of a feedback control system at a natural vibration frequency and amplifies especially the natural vibration frequency component included in the control deviation to obtain the variable (u). As a result, the control deviation is reduced and the performance of a controller is improved.
