Title:
PLANT CONTROL DEVICE
Document Type and Number:
WIPO Patent Application WO/2004/006029
Kind Code:
A1
Abstract:
A plant control device for controlling a plant as a control object by an adaptive controller capable of suppressing excessive correction when a spike-shaped external turbulence is applied and maintaining a preferable control. 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 adjustment mechanism (42). The parameter adjustment mechanism (42) multiplies the updated component d of the model parameter vector by a correction coefficient KID to calculate a corrected updating component KID·dѲ, which is added to the previous value Ѳ(k-1) of the model parameter vector to calculate the current value Ѳ(k). The correction coefficient KID is updated from “1.0” to a value near to “0” when a spike response increasing the absolute value of the high-pass filter output KACTHP is detected.
