Title:
内燃機関の排気系の空燃比制御装置及びプラントの制御装置
Document Type and Number:
Japanese Patent JP3592519
Kind Code:
B2
Abstract:
A plant control system controls a plant (E) modeled as a discrete-system model including an element relative to a response delay of the plant (E). The plant control system includes an actuator (1) for generating an input (LAF) to the plant (E), a first detector (6) detecting an output from the plant (E), and a second detector (5) for detecting the input to the plant (E) which is generated by the actuator (1). An identifier (25) (in unit 13 in Fig. 1) identifies parameters to be established of the discrete-system model based on data (VO2) representing an output of the first detector (6) and data (kact) representing an output of the second detector (5). A manipulated variable determining unit (13) determines a manipulated variable (KCMD) which determines the input to the plant (E) to control operation of the actuator (1) such that the output from the first detector (6) will be equalized to a predetermined target value (VO2/TARGET), according to a predetermining algorithm using the parameters of the discrete-system model which are identified by the identifier (25).
