Kind Code:
B2
Abstract:
A feedback controller of the present invention comprises a controller (21). The controller controls to input a reference value (R) instructing a controlled variable (eo) output from a controlled object (10) operated in accordance with a manipulated variable and a controlled variable (10), to calculate a manipulated variable such that the controlled variable (eo) is equal with said reference value (R), and to supply the calculated manipulated variable the controlled object (10). The controller (21) has a transfer function Gf (s), and functions to generate the following response waveform f (t) to a disturbance. That is, a response waveform of the controlled variable (eo) at the time when the disturbance is added to the controlled object (10) is set to f (t), a response waveform of said controlled variable (eo) in an opened loop state that feedback of said controlled variable (eo) 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 (t = 0) in which the disturbance is added to the controlled object (10), each differential value of the response waveform f (t) up to at least a degree (2g + d - 2) is equal to each differential value corresponding to the response waveform p (t), and at finite time (t = Tc), 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.
