Claims

[Claims for Utility Model Registration] (1) Among the components constituting the control system, the transfer function of the component having at least one integral element is expressed as _G2 , and the transfer functions of the other components are collectively expressed. A control system that switches between the first round transfer function G ₀ =G ₁・(1+G ₂ ) and the second round transfer function Goo=G ₁ in response to switching of the switch means _. a power supply means for supplying a predetermined power supply voltage to the control system; and a power supply means for controlling the switch means so as to make the open-loop transfer function of the control system the second open-loop transfer function for a predetermined period when the power supply voltage is activated. 1. A control circuit comprising: a switch control means for controlling a switch; (2) When the transfer function of a component having at least one integral element among the components constituting the control system is expressed by _G2 , and the transfer functions of the other components are collectively expressed by _G1 . , a control system that switches between a first round transfer function G ₀ =G ₁ · (1 + G ₂ ) and a second round transfer function Goo = G ₁ in response to switching of a switch means, and a control system that changes to a plurality of levels. a reference signal output means for outputting a reference signal and applying the reference signal to the control system in order to change the control state of the control system according to each level; and the control system for a predetermined period when the level of the reference signal changes. 1. A control circuit comprising switch control means for controlling said switch means so as to make the one-loop transfer function of said second one-loop transfer function.
