Title:
CONTROLLER FOR PLANT
Document Type and Number:
Japanese Patent JP3942970
Kind Code:
B2
Abstract:

PROBLEM TO BE SOLVED: To provide a controller for a plant capable of maintaining good controllability and suppressing excessive correction when a disturbance is exerted in a spike state when controlling a plant which is the controlling object of an adaptive controller.
SOLUTION: A detection equivalence ratio KACT is inputted into a high pass filter 3, and a high pass filter output KACTHP is inputted into a parameter adjusting mechanism 42. The parameter adjusting mechanism 42 multiplies an update component dθ of a model parameter vector by a correction factor KID and calculates a correction update factor KID×dθ, adds it to a previous value θ(k-1) of the model parameter vector, and calculates the present value θ(k). The correction factor KID is changed from 1.0 to a value close to 0 when detecting a spike response which increases the absolute value of the high pass filter output KACTHP.
