A feedback controller of the present invention comprises a controller. The controller controls to input a reference value instructing a controlled variable output from an object operated in accordance with a manipulated variable and a controlled variable, to calculate a manipulated variable such that the controlled variable is equal with said reference value, and to supply the calculated manipulated variable to the object. The controller has a transfer function Gf, and functions to generate the following response waveform f (t) to a disturbance. That is, a response waveform of the controlled variable at the time when the disturbance is added to the controlled object is set to f (t), a response waveform of said controlled variable in an opened loop state that feedback of said controlled variable is turned off is set to p (t), a relative degree of the disturbance is set to "d", and a relative degree of the controlled object is set to "g", at time in which the disturbance is added to the controlled object, each differential value of the response waveform f (t) up to at least a degree (2g + d - 2) is equal to each dif- ferential value corresponding to the response waveform p (t), and at finite time, each differential value of the response waveform f (t) up to at least a degree (2g + d - 2) becomes zero and after the finite time, the differential values relative to all degrees become zero.
