Abstract:
A control system for determining a control function for a control device on the basis of a transfer function of an object to be controlled and for adjusting an operation quantity of an object to be controlled in accordance with the determined control function, wherein control function of a first control device is determined so that a one-cycle transfer function of the object to be controlled and the first control device coincides with a predetermined first transfer function, a control function of a second control device is determined, in a closed loop control system including the object to be controlled and the first control device, so that a transfer function from a disturbance applied to the object to be controlled to a state variable of a point at which the disturbance is applied to the object to be controlled, and a sum signal indicative of a sum of outputs of the first and second control devices is used as an operation quantity of the object to be controlled.
