Abstract: PROBLEM TO BE SOLVED: To provide a control apparatus of a plant to stably control output of the plant like an exhaust system of an internal combustion engine including a catalyst device to set a predetermined target value with high accuracy. SOLUTION: The target exhaust system E as a plant is modeled, and a parameter to be set by the model is identified by using data (detection data of output of the plant) of output VO2/OUT from an O2 sensor disposed downstream of the catalyst device 3. Whether the identification processing is stable or not is determined. When the identification processing is stable, an operating amount for regulating input to the plant E is calculated by using an identification value of the parameter to converge the output VO2/OUT from the O2 sensor into the predetermined target value VO2/TARGET. When the identification processing is instable, the parameter of the model is set to be a predetermined value, and the operating amount is calculated by using the predetermined value.
