Title:
CONTROLLER FOR PLANT
Document Type and Number:
Japanese Patent JP3304845
Kind Code:
B2
Abstract:
PROBLEM TO BE SOLVED: To provide the controller of a plant for preventing the drift of an adaptive parameter, and continuing stable adaptive control even when the adaptive control is continuously executed in a normal state.
SOLUTION: An oblivious coefficient vector δ is multiplied by a previous value d θ hat (k-1) of the updated components of an adaptive parameter vector, and components obtained by multiplying an identification error eid(k) by a prescribed gain are added so that this time value dθ hat (k) of the updated components can be calculated. Then, the updated components dθ hat (k) is added to an initial value θ hat (0) of the adaptive parameter vector so that this time value θ hat (k) can be calculated (a figure (b)). The element of the oblivious coefficient vector θ is set to be more than 0 and less than 1 except for an element corresponding to an adaptive parameter b0.
