Title:
CONTROLLER FOR PLANT
Document Type and Number:
Japanese Patent JP3304844
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: When the value of an identification error eid(k) of an adaptive parameter is ranging from -η to +η, an output eida(k) is set as '0' by a non-linear filter B51, and the adaptive parameter is calculated by using the output of the non-linear filter B51. Thus, it is possible to prevent the storage of a fine identification error generated due to a difference between a model assumed on design and the characteristics of an actual plant or the influence of disturbance, and also it is possible to prevent the drift of the adaptive parameter.
