  "textContent": "The present invention provides a control apparatus for a plant, which can suppress excessive correction for a spiky disturbance being applied and maintain a good controllability, when controlling the plant, which is a controlled object, with the self-tuning regulator. A detected equivalent ratio KACT is input to a high-pass filter 33, and a high-pass filter output KACTHP is input to a parameter adjusting mechanism 42. The parameter adjusting mechanism 42 calculates a corrected updating vector (KID . d &thetas;(k)) by multiplying an updating component d &thetas; of a model parameter vector by a correction coefficient KID, and adds the corrected updating vector to a preceding value &thetas;(k-1) of the model parameter vector, to thereby calculate a present value &thetas;(k). The correction coefficient KID is changed from \"1.0\" to a value near \"0\" upon detection of the spiky response where an absolute value of the high-pass filter output KACTHP increases.",
