摘要： A control system for a plant is provided. This control system can control the plant more stably, when the model parameters of the controlled object model which are obtained by modeling the plant, which is a controlled object, are identified and the sliding mode control is performed using the identified model parameters. The model parameter identifier (22) calculates a model parameter vector (θ) by adding an updating vector (dθ) to a reference vector (θbase) of the model parameter. The updating vector (dθ) is corrected by multiplying a past value of at least one element of the updating vector by a predetermined value which is greater than “0” and less than “1”. The model parameter vector (θ) is calculated by adding the corrected updating vector (dθ) to the reference vector (θbase).

摘要： A vehicle controller for controlling the air-fuel ratio of an engine is provided. In one embodiment, the controller comprises a first exhaust gas sensor provided downstream of the catalyst for detecting oxygen concentration of exhaust gas, a first decimation filter connected to the first exhaust gas sensor, and a control unit connected to the first decimation filter. The control unit determines a manipulated variable for manipulating the air-fuel ratio. The first decimation filter oversamples, low-pass filters and then downsamples the output of the first exhaust gas sensor. The first decimation filter can remove chemical noise from the output of the exhaust gas sensor. In another embodiment, a second decimation filter is connected to a second exhaust gas sensor provided upstream of the catalyst for detecting the air-fuel ratio of the exhaust gas. The second decimation filter oversamples, low-pass filters and then downsamples the output of the second exhaust gas sensor. The second decimation filter can compensate the shortage of resolution of the air-fuel ratio sensor.

摘要： A control system for a plant is disclosed. According to this system, a model parameter vector of a controlled object model which is obtained by modeling the plant, is identified. A controller controls the plant using the identified model parameter vector. An identifying error of the model parameter vector is calculated, and an updating vector is calculated according to the identifying error. The updating vector has at least one first element which is relevant to an input or an output of the plant, and a second element which is irrelevant to the input and the output of the plant. The updating vector is corrected by multiplying a past value of at least one first element of the updating vector by a predetermined value which is greater than “0” and less than “1”, and multiplying a past value of the second element of the updating vector by “1”. The model parameter vector is calculated by adding the corrected updating vector to a reference vector of the model parameter vector.

摘要： A control system for a plant, having an identifier and a controller. The identifier identifies model parameters of a controlled object model which is obtained by modeling the plant. The controller calculates a control input to the plant so that an output from the plant coincides with a control target value, using the identified model parameters. The controller calculates a self-tuning control input, using the model parameters identified by the identifier. The controller further calculates a damping control input according to the rate of change in the output from the plant or the rate of change in a deviation between the output from the plant and the control target value. The controller calculates the control input to the plant as a sum of the self-tuning control input and the damping control input.

摘要： A target air-fuel ratio KCMD for an exhaust gas upstream of a catalytic converter is sequentially determined to converge the output VO2/OUT of an O2 sensor downstream of the catalytic converter to a target value VO2/TARGET, and the amount of fuel supplied to an internal combustion engine is controlled to converge the output KACT of an air-fuel ratio sensor to the target air-fuel ratio KCMD. While the amount of fuel supplied to the internal combustion engine is being thus controlled, the value of a deterioration linear function &sgr; whose variable components are represented by time-series data of the output VO2/OUT of the O2 sensor is determined. A central value of the square &sgr;2 of the value of the deterioration linear function &sgr; is determined as a deterioration evaluating parameter. A deteriorated state of the catalytic converter is evaluated on the basis of the value of the deterioration evaluating parameter.
